Steven,

The zap card drivers are loaded correctly and there don't seem to be any 
IRQ problem.
Here is what I get from    /proc/interrupts.
I'm not sure the sound card and eth0 using the same IRQ could be causing 
the problem?

           CPU0
  0:   17728993          XT-PIC  timer
  1:      44037            XT-PIC  keyboard
  2:          0                XT-PIC  cascade
  5:    9776462          XT-PIC  eth0, Intel ICH2
  8:          1                XT-PIC  rtc
  9:  103179821        XT-PIC  wcfxo
 10:  217202079       XT-PIC  nvidia, wcfxo, wcfxo
 12:     524504          XT-PIC  PS/2 Mouse
 14:     165140          XT-PIC  ide0

NMI:          0
