Wait a minute. Is this the zimage from my original floppy image?
That one was the stock BL3 loop kernel.

You shouldn't need to add anything. Try using one of the Slackware
kernels. I believe that there's at least one that supports zip
disks.

You can change it, too. Just replace the zimage on the disk with a
different one. Perhaps bare.i from Slackware will work?

*red flag*! Only one dotclock rate is supported (28.32)?!

Try this modeline. Add it with the others in the appropriate section
of XF86Config. Comment out the other 640x480 ones while you're at it.
This is 67.4 Hz, 33.7 KHz so you will need to adjust the range of
allowed sync ranges.

Modeline  "640x480" 28.32   640  656  720  840 480 481 484 500 -hsync -vsync

I found a website which may be relevant.

It would probably be easier to just browse through the April postings.
