yup - 32bit the 5365 build. however, i've just re-installed it again cause the sound was problem. it's now randomly hanging on first boot. weird.
what 5.1 card you using? when i installed vista x86 5365 it ran slow as fuck, looked the mutts nutts but it was unusable until i forced some drivers for sound, gfx and network onto it.
it's some cheapo 'Trust' one i got off dabs... the gameport doesn't work - got the sound working now everything else hardware wise is fine
Time to uninstall Build 5381.1 doing the rounds and seems loads better. However - if you just wait till end of may - public release of Beta2 will be out - i.e. wont expire in 14 days
