No, that was my misinterpretation.
The BIOS_VERSION call is broken for different reasons,
and my original all-inclusive patch has a fix for it too.  :)

Here's a go, 64-bit kernel (3.2.8), 32-bit userspace:

Dell laptop SMM driver v1.14 21/02/2005 Massimo Dal Zotto (dz@xxxxxxxxxx)
ioctl32(i8kctl:1474): Unknown cmd fd(3) cmd(80046980){t:'i';sz:4} arg(ff8b1fd8)
on /proc/i8k
ioctl32(i8kctl:1475): Unknown cmd fd(3) cmd(c0046986){t:'i';sz:4} arg(ff90ed5c)
on /proc/i8k
ioctl32(i8kctl:1475): Unknown cmd fd(3) cmd(c0046986){t:'i';sz:4} arg(ff90ed5c)
on /proc/i8k

I'll reboot/redo that again with strace shortly.
