Rather unusual for ttyS[01] - are you shure these are the right addresses?
You said they're onboard, am I right?

Just to be sure: Are these ___modified___ ISA ports or are they PCI so
you try to share the interrupts?
Emm - what does 'cat /proc/interrupts' tell us?

Well spotted :-) - That may be the reason why _only_ his /dev/ttyS0 works:
setserial _fails_ to set that weird address (because of the overlap) and
keeps the default 0x3e8 .. 0x3ef, which is much more sensible for an
onboard standard ttyS port :-))
Brian: maybe you should change the '0' at the end of your port addresses
to '8' and doublecheck that the address is correct then.
