Great, thanks for testing!

Not sure if that's worth it, my feeling is that we are stuck with
fbdev on a lot of other workstations of the era, so unless someone
puts significant energy into converting all the others as well, there
is little benefit of changing this one. It would be a little different
on platforms that actually run a regular Debian distro kernel that
is shared with modern machines.

Since you have already spent the time to build and test a kernel with
this patch, can you do one more test here and check the text size
reported in the atags on this machine and the actual text sizes you
get from both vgacon and cyber2000fb?
