Bug#570491: seems to work with 2.6.34

[Michal Suchanek <hramrach@centrum.cz>]

Hello,

this is not related to KMS, it would lock up with or without KMS with
kernels 2.6.32 and 2.6.33.

2.6.34 seems to not have this issue but I cannot be sure as the
problem is not reliably reproducible.

Thanks

Michal
