I can do that, and rename the older program, and hope the current zgv 
works with current libraries.  Otherwise I would need to upgrade those as 
well (libvgagl, libvga, libjpeg, libpng, libtiff, libz libm libc.so., 
ld-linux).

Will I need to upgrade those to the SW91 libc for the new svgalib to work? 
If so I would probably also need to upgrade the full libc, since when I 
tried using the SW71 libc.so with the SW81 libc, the compiler and ar and 
other things stopped working.

It might be a lot simpler just to use your small usb-storage kernel for 
downloading pictures and reboot to the regular 2.2.16 (or 2.2.26 - if it 
works with everything now on my computer).

The svgalib package contained libvgagl and libvga.  I might need to 
upgrade just those.  The rest is tests, documentation, config files, and 
restoretextmode and related programs (not resizecons, I must have 
found that somewhere else).

With BL2 I am using the delilinux Xvesa, but I could use the BL3 
statically compiled one instead, which is probably newer.  I have not 
tested it with your kernel.  I think I also had the same problems with 
plain X as with Xvesa - can't establish listening socket.

I will try your kernel with BL3 and the Xvesa that comes with it.

If I would have to upgrade libc to use your custom kernel, I will stick 
with the small usb-storage-only one for a while and try to add framebuffer 
support to my own 2.2.16 again.  Or maybe someone can get a 2.2.26 kernel 
to work with cameras as well as ipods.
