HI
I too thought this of RME, their website is a bit ambiguous to say the 
least.

I can say the cheap(!?) Hammerfall lite I have works on all the Linux 
system I have used, with very low latencies.

He should contact RME direct and let us know the outcome, they seem to 
be a Linux friendly company.
