It is still there, but the module was renamed to thinkpad-acpi.  AFAIK, I
didn't break or remove any support for the T23, so please report any bugs.

Nothing, AFAIK ;-)  And I should know, since I am the ibm-acpi/thinkpad-acpi
maintainer.

That said, bugs could have crept in, I certainly have no T23 (or T3x) to
test those codepaths.  In fact, there was a bug introduced in the OLD_LED
support recently, that I'd never know about if an user had not reported it.
