Yes, I agree it sounds VERY much like an interrupt problem.  Here is
what I have found from experimenting (asside from that things still do
not work):

Anyone who is interested in helping, take a look through and let me
know any new ideas on what to try....

Here is the list of interrupts as they are now Interrupt List:

 0: timer
 1: keyboard
 2: cascade
 3: Serial 2
 4: Serial 1
 5: Modem (Serial 3)
 6: ?
 7: Parallel Port
 8: ?
 9: Linksys Ether16 network card (NE2000) (eth0)
10: DiamondMM Stealth 3D 3000 (2MB) Video Card
11: Creative Labs Ensoniq audio card
12: Intel 10/100 Ethernet Controller (eth1)
13: FPU
14: IDE0
15: IDE1
 

I removed the sound card and everything goes back to normal, I put the
sound card back in and the same problem occurs.

I swapped out the PCI cards (Intel ethernet card, video card, sound
card), and put them in a number of configurations and there was no
change except for the periodic change in IRQ, but still none
overlapping.

As the board is fairly old, it is almost certain I have the latest
bios for the motherboard, but it is worth checking just in case.

In the bios, PnP OS is set to no already.

The top command reveales nothing spectacular - XF86_S3V is never using
more than 8% of the CPU time, and that only briefly on startup, then
it goes to the bottom of the list and idles.

The system is full accessible over the network and routes network
traffic just fine, runs an xterm, etc.  Just the input to the X-Server
does not work.

The /var/log/messages file relevant to loading the IS1371 driver is as
follows:

I/O ports do not overlap anywhere.  Here is the /proc/ioports
contents:

Here is the output of the `lspci -vv` command in case anyone can make
some use of it to help solve the problem:
