Same three functions, one more NID each. Those two shells started no plugins at
all and sat on a black screen; both reach an interactive XMB now.

sceKernelLoadModuleVSH, sceKernelGetModel and sceImposeSetStatus each appear
under a different NID in 3.95/4.05, 6.00/6.20 and 6.31/6.39. Without the load
one those shells started no plugins at all and sat on a black screen.
Identified the same way as the 5.xx set: for each firmware, the modulemgr export
with sceKernelLoadModuleVSH's callee set, and the vshbridge export whose body is
the user-level check 6.61 wraps sceKernelGetModel in - which is also the only
SysMemForKernel import those shells actually call.
3.95 and 4.05 now reach an interactive XMB.

sceKernelLoadModuleVSH, sceKernelGetModel, and four of sceImpose_driver's calls
already have implementations; 5.xx just asks for them under different NIDs, so
the 5.50 shell got nothing back. Each one was identified by disassembling that
firmware's own module and comparing the body against 6.61's, where the same
function is exported under a name - the pairs are instruction-for-instruction
identical apart from context-struct offsets.
GetModel was the one that mattered most: unresolved, vshbridge handed the shell
a garbage model number, and it went looking for PSP-3000 resources on a dump
that has none.

sceKernelAllocHeapMemory and sceKernelAllocHeapMemoryWithOption return a
pointer, so failure has to be 0 - JPCSP documents it as "the address of the
allocated memory block, or NULL on error". We passed BlockAllocator::Alloc's
result straight out, which is (u32)-1 when the allocation fails, and returned
UID error codes for a bad heap id. Anything checking for a null pointer took
those for success.
Mostly small stubs:
- sceImpose: GetParam/SetParam/Changes/SetStatus, plus the 6.60 alias of
sceImposeGetBatteryIconStatus. Also fixes that function's first output - it
is a plain "is it charging" boolean, not a BATTICON_ value. We wrote
PSP_IMPOSE_BATTICON_NONE (0x80000000) there, which games ignore but which the
VSH reads as "no battery" and draws the empty-battery indicator for. These
are the bulk of the traffic: the VSH calls sceImposeChanges once a frame, so
this alone removes ~10000 trapped calls from a boot.
- SysMemForKernel: sceKernelSetRebootKernel, sceKernelSetUmdCacheOn.
- scePower_driver: scePowerSetWakeupCondition.
- sceHprm_driver, sceUsb: one NID-named call each, as in JPCSP.
Three groups are deliberately left unresolved, with comments explaining why,
because resolving them lets real flash0 drivers walk into hardware we do not
emulate and the boot dies where it used to reach the shell:
- ThreadManForKernel mutex/fpl NIDs: the NAND and ID storage drivers use these
to init, then poll the NAND controller at 0xbd101300 forever.
- InterruptManagerForKernel intr registration: 31 calls, then a stall in GE
list execution with no plugin module ever started.
73 unresolved import hits over 37 distinct module/NID pairs remain in a VSH
boot, mostly sceSysEventForKernel, sceSuspendForKernel and the various
*_driver modules that need real hardware behind them.
The sceImpose savestate section goes to v2 for the two new state variables.
