Drivers in general yes ;-)
This driver, probably not.
But the issue is that a lot of drivers "depends on X86_64" or such,
where only "X86" is the arch symbol. You could add "X86 && X86_64" to
really build on x86 64-bit only.
I didn't check this driver, but this has mostly popped up since UM got
PCI support some time ago (which I added.)
