Only changes between our 2.6.26.2-1 and 2.6.26.3-1 are some minor
framebuffer changes in config. If i have a look at the different
patchsets between the two versions i don't see something which could be
the reason between work and not work.

Hmm, one user also reports that he have no problem when using a vanilla
2.6.26 as guest kernel. But there must be some reasons when different
distributions notice a major problem between 2.6.25 and 2.6.26 with
their stock kernels. Although i don't even know if our few reports here
are very representavive...
