Because some stuff to the now-dead uart driver never made it past
linuxppc-2.5.  Specifically I believe it was 8xx_UART that didn't.

Right.  But we don't have ethernet and serial on SMC1.  What I was
talking about is we ask what driver should take care of SMC1, SMC2,
SCC1, and so on.  You could just be smart and not configure 2
drivers to use the same SMC or SCC as well.  What Robert was talking
about was making the system smart enough to not let you do it.  And
with 2.6 Kconfig syntax, this isn't as painful as it would have been
