graf_chokolo's progress in decrypting PS3 Firmware 3.50, and today he has made available to the PlayStation 3 Wiki (linked above) his PS3 hypervisor reverse-engineering work to date, as follows:
HSPRG
The hypervisor stores a pointer to some structure per LPAR in HSPRG0 register. There are actually 2 HSPRG0 values: one for each thread of Cell CPU !!! There is a HSPRG0 array at 0x8(-0x69A0(HSPRG0)) + 0x20.
LPAR
LPAR = Logical Partition
lpar1 starts at 0x(unknown), and its believed to be the memory space wherre lv1 stores its variables, flags and other data.
lpar2 starts at 0x80000000000 and it's believed to be the memory space where lv2 stores its variables, flags and other data.
The pointer to active LPAR is stored at -0x67E8(HSPRG0).
vtable
0x0033CA40 (3.15)
Member variables
offset 0x38 - some pointer
offset 0x50 - LPAR id (8 bytes)
offset 0x70 - pointer to VAS id bitmap
offset 0x78 - power of 2 of word size from VAS id bitmap (4 bytes), equal to 6
offset 0x7C - number of 64-bit words in VAS id bitmap(4 bytes)

After swapping back in my original 160GB HDD, I was still getting the 8002F281 error. I ended up having to do a full PS3 Reset and reformat of the 160...
