Hello Linus,
Looks like this one liner patch never made it... Hopefully, it'll go in
before you release rc9 or 2.6.29.
Best,
Mathieu

Subject: [PATCH] thinkpad-acpi: fix module autoloading for older models

Looking at the source, there seems to be a missing * to match my DMI
string. I mean for newer IBM and Lenovo's laptops you match either one
of the following:
MODULE_ALIAS("dmi:bvnIBM:*:svnIBM:*:pvrThinkPad*:rvnIBM:*");
MODULE_ALIAS("dmi:bvnLENOVO:*:svnLENOVO:*:pvrThinkPad*:rvnLENOVO:*");
While for older Thinkpads, you do this (for instance):
IBM_BIOS_MODULE_ALIAS("1[0,3,6,8,A-G,I,K,M-P,S,T]");
with IBM_BIOS_MODULE_ALIAS being MODULE_ALIAS("dmi:bvnIBM:bvr" __type "ET??WW")
Note there's no * terminating the string. As result, udev doesn't load
anything because modprobe cannot find anything matching this (my
machine actually):
udevtest: run: '/sbin/modprobe dmi:bvnIBM:bvr1IET71WW(2.10):bd06/16/2006:svnIBM:pn236621U:pvrNotAvailable:rvnIBM:rn236621U:rvrNotAvailable:cvnIBM:ct10:cvrNotAvailable:'

Len, please consider this for 2.6.29. It is an obvious one-liner.
