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.
