I'm on gentoo too, running a terratec ews88mt also with the ice1712. 
Is there a good reason for you to stay with a 2.4 kernel? newer 2.6 
kernels do perform excelent in therms of audio. I use the ck-sources. 
With it, jack runs fast and smoth - never got it better bevore. 
upgarading kernel can take some time but if you can... I would.

      Latest version available: 2.6.12_p3-r1
      Latest version installed: 2.6.12_p3
