Good question!  ``show config'' just shows "Device: 2, Name: COM1,
Type: Embedded, Enabled: Yes, BaseAddr: 3f8, IRQ: 4, DMA: None"
[simimar entry for COM2, with the expected addr/IRQ diffs].

Not very instructive on the topic of chipsets and such. :(

It never gets far enough for that to be a problem. :)

OK, I've gotten this far now - I'll work on compiling up a gdb on the
x86 which understands alpha (Doug sent me a configure line earlier)
and start running serial cables. :)
