You are, in fact,  correct.

I had forgotten that my alpha's kernel config had wildcarded entries
for the on-board com ports, which explains why they got com4 and com5.
If I instead had
	com0    at      isa? port 0x3f8 irq 4
	com1    at      isa? port 0x2f8 irq 3
like my i386 boxes have, then on the alpha I would have seen the puc
com ports on com2..5.

So, in an addendum to my previous post, it appears that hard coded
numbers take precedence over wildcard ones.  I apologise for any
confusion my previous mail may have caused.

Andrew; thanks for the clarification.

Luke.
