T41 suspend to ram finally working

After an upgrade from kernel 2.6.17 to 2.6.19 I noticed that my Thinkpad T41 was no longer hot. A quick look through the kernel changelogs reveiled that the nasty ACPI bug has finally been fixed. My laptop now has all the properties of a Laptop again.

[PATCH] radeonfb sleep fixes
Many IBM Thinkpad T4* models and some R* and X* with radeon video cards draw
too much power when suspended to RAM, reducing drastically the battery

lifetime.  The solution is to enable suspend-to-D2 on these machines.  They
are whitelisted through their subsystem vendor/device ID.  This fixes
