has any tried to see if the recent apple graphics update solved the problem with the decklink cards?

i've got myself in a bit of a pickle. i need to send two machines on a job with working decklink hd-sdi input. i have it working fine on a machine running 10.5 but that's not the machine i need to send. the two machines going on the gig are fairly new and came with 10.6 preinstalled. turns out there have been some firmware updates that won't allow these machines to run 10.5 (at least not that i've been able to make work)

i'm away from the computers until next week but then i'm going to see if i can get the decklink cards working on either 10.6.0 or on a machine with a fully updated os (my preference if anyone else has gotten them working and stable).

any thoughts greatly appreciated.
