Curse you folks with a video display! :)

OK. So when I wrote all of this initially, there was, I could have
sworn, a good reason for doing 'serial_fixups' as an asm routine, and
not just a define or C func. But, I can't recall why now.
So if you'd be so kind as to whip up, and test, a patch which switches
us to defines, or a C func, whichever ends up being easier, I'd
appreciate it. Thanks.

'cmon, you know you want to. :)
