Didn't test it yet with 2.6.23-rc2 or rc3, but up to 2.6.22 it was fine :)

Regarding the option to blacklist VIA in the module:

parameter like "honours inactive bit" to override this.

Perhaps there are newer VIA Chips out there, that indeed do this and some 
users trigger happy enough to test this. :)
