I don't know, I just have noticed some compatibiity similarities, I'd like to see someone run some benchmarks obviously they aren;t going to be 100% the same different kernel etc. but surely somehow someone can figure out if they are using a "unified style" driver or something... IF Microsoft is pushing for Linux to get all these drivers I'd say that Linux users need to STFU for a little while. Sheesh,
could you imagine ALL the Vista drivers IF they actually could work on Linux?(well NOT the driver but the binary) ;)
