The weird thing here, IMHO, is that the old workaround like switching to 2.6.12
kernels (which did the trick for me), using some "hacked" preloaders (which
didn't do the trick for me) and all [1] don't work this time.

Only the Cedega fix *seems* to work (According to *one* post on the gentoo forum
[2])

If you want some debugging informations, just give me the way to look for them
and I'll give them.
