Another ThinkPad R40 setup

[Tobias Roth]

adjusting the bios settings for the irq is the way to go, not just
disabling devices. if your R40 is anything like my T30, the settings
you will find here (in my comment to Kevins entry for the T30) will
help you use all devices at the same time.

i already mentioned thise a few times on mobile/current.

good luck, t.
