V.90 modems

[Boba Fett]

I know that the 56Flex and X2 modems are compatible with 
Linux.  Unfortunately, from what I've read is that since they use
software compression Linux will only get they "regular" 
33.6kps transfer speed.  I have a USRobotics X2 modem on 
my RHL 5.1 system.  If I software upgrade to V.90 will I be able
to get a faster connection. or are all Linux users doomed to 
33.6kps dial-up transfer rates?
