thanks, applied.

yeah, that seems to be the case:

in drivers/pnp/pnpbios/Kconfig:

config PNPBIOS
...
depends on ISA && X86 && EXPERIMENTAL

in arch/x86/Kconfig:

if X86_32
config ISA

it seems the PNPBIOS has not infested the 64-bit world, so we wont ever
see this with a 64-bit kernel:

extern u32 pnp_bios_is_utter_crap;
pnp_bios_is_utter_crap = 1;
printk(KERN_CRIT "PNPBIOS fault.. attempting recovery.\n");
