High interrupts w/ Cisco 350 card

I'm running 5.4-RELEASE-p6 on a Toshiba Tecra M2 laptop.  My network
card is a Cisco 350 PCMCIA card.  I'm experiencing a very high rate of
interrupts during heavy network traffic.  The laptop becomes very
sluggish to respond.  The more traffic through the interface, the higher
the number of interrupts and the more sluggish the laptop becomes.  I've
searched the mailing list archives and the web, but haven't been able to
find anything relevant.  This Cisco card works fine in every other
laptop I have.  I suspect it might be a cardbus problem, but I don't
know how to resolve it or troubleshoot it any further.  I've tried
disabling ACPI and that hasn't helped.  Has anyone experienced this or
have any suggestions?  Any help would be much appreciated.

Here is the output from a "vmstat -i", a "systat -iostat", and my boot
time dmesg.  There are no other errors showing up in any of the logs or
on the console.
