Will the wheel mouse also work with gpm? My partner liked pasting between
terminals with it.
We have several wheel mice, PS/2 or USB-with-PS2-adaptor and I was unable
to get them (I may have only tried one) to work with the wheel even as
PS/2. Does BL support wheel mice?

I tried it with an ohci and all the modules inserted, but it did not find
the camera or the card reader (with CF card) that both worked in DOS and
with your newer kernel. It might work with certain kinds of usb storage
devices but not these. I did not get the complaint about finding a device
that was not assigned to any active driver because of unrecognized id's.
If you like, I can repeat the experiment and post the exact results, but
they did not seem promising.

But someone said it worked with their iPod.
Why would they include the module if it does not work at all?
I read something about backporting from 2.4.

I think Steven may have compiled zgv a few years ago. Would he have used
code from SW3.x or 4.0 rather than recent source code?
If you compiled zgv statically with the latest vgalib code would it work
with kernel 2.2.26 and 2.4.31? Then people would not need svgalib at all
with your newer kernel, just to look at photos. (It would still be needed
for the delilinux links2). I don't know if uClibc would cause problems.

Do you want to statically compile a later zgv? I should probably upgrade
svgalib anyway to work with newer graphics cards.

I was thinking of booting BL3 from floppy disks (with lilo) and using it
to download photos. But DOS is working just as well, from a single boot
disk with space for a viewer and even a few low-res photos.

With BL3 kernels and the framebuffer kernel you made, I have to
mount -t msdos /dev/..... but with BL2 I don't need to specify the file
type. Why? I forgot what your new kernel requires.
