I am planing on getting Acer Travelmate 803Lci which uses the O2 Micro
CardBus controller.

This is a snippet from lspci output from 803Lci I found on the net
(different sites have very similar outputs).
It looks that O2 Micro controllers in general add quite some latency and
should be avoided for professional audio as RME and Derek have pointed
out.
But are all O2 Micro controllers equally "bad"? Do we have any coment
from your frined or any other user of Acer?
The device found in 803Lci should be O2 MICRO Inc. OZ711M1 according to
the document http://www.tssc.de/download/docs/listofsupporteddevices.htm
(cached by google).
Thanks and take care,
Miha...

BTW - I have a friend who designs cardbus
controllers for O2 Micro, so I
can ask questions from the inside if we need some specific information.
