Yes I think this makes most sense, at least for now.

Parity check etc should be OK. As I understand it it is just the master
abort (which is kind of a timeout if the target function doesn't
respond) which hurts. If the cardbus bridge translates this into
a target abort it confuses the PCI framework of at least some
architectures. (Istr some alphas check, but other ports rely on reading
all-ones.)
The problem with enabling after the scan is that "after the scan
is before the scan" on cardbus. I'd say we can live without
the MABRT bit set. Needs some testing of course.

best regards
Matthias
