Unfortunately in this type of situation, I'm not sure you'd get much
help by using an older kernel - the driver may well not behave itself
well enough to still work under Xen... At least, I think that is still a
problem in Xenified Linux as it is under HVM - drivers in Xenified Linux
are modified to "understand" Xen, and that's not going to work with
binary drivers. However, I may be wrong. Someone with better
understanding of this may be able to correct me (or say I'm right).
