Well, given all the distros will enable that, might as well be #if
!defined(CONFIG_BREAK_SOME_HARDWARE_BUT_VGA_SCROLLING_WILL_BE_IMMEASURABLY_FASTER).
All distros on 1 out of 29 architectures?

It's a fairly popular architecture. I imagine most distros wouldn't enable it even on x86. It's an incredibly obscure setup from the evidence of how long it took to get reported.
