[LAU] Horrible number of xruns in Jack (Emu card)

I hope someone can help me with this.

I have:

Athlon64 Dual-Core 6000+
2GB DDR3 RAM, running dual-channel
3 x SATA hard disks
Emu 1212m sound card
Ubuntu Studio 7.10 (Gutsy, I think)

Trying to run JACK at 44.1khz, at a 128 sample buffer I'm getting on the 
order of 50-60 xruns a second. Even at a 4096 sample buffer, I was 
getting one xrun every 2 seconds. I would think this setup should be 
able to handle a 64 sample buffer without any trouble.

The one caveat is I did have to compile the latest stable ALSA from 
scratch, so that my sound card would work. Could it be related to the 
still-beta driver for my Emu card? Or maybe I need to recompile ALSA 
with some options?

Thank you for any help.
