I wonder if this really true, in that context. I know that ThinkPads do
a lot of stuff in firmware/smbios. Your smapi/hdaps modules are a proof
that it does quite a lot of stuff, which means that it might be a lot of
code there, which may needs bugs too. Not sure if someone already looked
at that, but it could be concerning. Not wanting to FUD, though.

You may want to try flashrom, from the coreboot project, but here (on a
T61 too) it won't work:

corsac@hidalgo: sudo flashrom -r bios.img
flashrom v0.9.0-r631
No coreboot table found.
Found chipset "Intel ICH8M-E", enabling flash write... WARNING: SPI Configu=
ration Lockdown activated.
OK.
Calibrating delay loop... OK.
No EEPROM/flash device found.
If you know which flash chip you have, and if this version of flashrom
supports a similar flash chip, you can try to force read your chip. Run:
flashrom -f -r -c similar_supported_flash_chip filename

Note: flashrom can never write when the flash chip isn't found automaticall=
y.
