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

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

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.
