PCI doesn't really have a problem with IRQs, so this isn't anything to worry 
about.

You can get tons of things working simultaneously in Rosegarden, at least as 
far as the MIDI side of things.

The bigger problem is audio.  Getting JACK to use more than one soundcard is 
more complicated a subject than I've ever felt like delving into.  I have no 
idea what would happen in that case.

It's probably 48,000, actually.  Mine is, and I don't think the rate can even 
be changed.

Like Brendon said, there's no hardware synth on the 7.1.  MIDI in hardware is 
pretty much an obsolte concept.  The closest thing to a Roland Sound Canvas 
you can buy new today is some soft synth software from Edirol that simulates 
a Sound Canvas.  What little old school MIDI gear you can still buy today is 
almost exclusively at the $1000+ end.  Apparently that kind of thinking has 
influenced Creative as well.  None of their newer soundcards have hardware 
synths anymore.

So what you'd probably want to do, in the interest of avoiding figuring out 
how to solve complicated problems, is use the 5.1 for MIDI playback and the 
7.1 for JACK.  That should be no problem.  One of them will be "hw:0" and the 
other "hw:1" and you just have to figure out which is which.

Doubt it.

The default is to compile all of them, and to compile everything as modules.  
Depending on how user friendly your distro is, it will probably mostly just 
work after you boot with the new hardware in.

If you can't do anything decent with it because it's an ill-conceived consumer 
piece of crap, then I can attest to using a 5.1 along with an Audiophile 
2496.  I run JACK on the Audiophile, and the other one just does MIDI stuff.  
I have them linked through SPDIF, and it works spiffy keen like.

Or it did, actually.  I've got the emu10k1 out at the moment, but that's a 
different story.
