[ale] PCI-e multiport serial cards

[kaboom at oobleck.net (Chris Ricker)]

Anyone got experience with PCI Express multiport serial (RS-232) cards 
under Linux? I'm looking for 8 port models, which appears to limit me to 
the following vendors:

Moxa
Perle
Aaxeon
Softio

I've never used anything from them, so I'm just trying to find out who 
makes good drivers, who has stuff that's a pain to configure, etc

later,
