well i've been using my aspire one on F10 since the day of the F10
release with the exa acceleration method, i'm scoring ~780 in glxgears with
glxgears -geometry 300x300+360+150
as the command, i've yet to have a X lockup or crash either and i'm
using compositing in xfwm4 too, and the plymouth solar boot works well
too. obviously not everyone is having such a good time with their intel
gfx hardware, but not everyone is having problems either ;)
