ia32 kernel on amd64 box?

I was wondering the same thing about peripherals. The README in aic79xx driver from adaptec states that the driver is supported on x86 only. So I was wary to spec model 39320 HBAs in x86-64 machines. I'm sure Adaptec is using the term "support" in the most corporate sense possible, but what if it really does scribble the disk under SuSE 64-bit kernel?
