The following patch fixes this regression (confirmed by Andrey).
Please queue it for 2.6.23. I'll come back later for another
try at sorting this all out.
PNP: remove SMCf010 quirk
If the quirk enables the SIR part of the SMCf010 device, the 8250 driver
may claim it as a legacy ttyS device, which makes the legacy probe in the
smsc-ircc2 driver fail.

I believe that this is gone as of 2.6.23-rc4-git3

Should be solved by 3b2b64fd311c92f2137eb7cee7025794cd854057, although
differently from the the patch suggested above. So the regression should
be gone a of -rc5.

BTW. Maciej Rutecki has said that "MCFG bug on hp nx6310" is not
a regression, so regression counter for ACPI == 0 (if I didn't
overlook something :))
