More ISC keyboard fixes

[Robert Lin]

I wrote a little program that fixes the brain-damaged way ISC switches
between virtual screens. Instead of the Alt-SysRq Fn method, this one
emulates the Xenix way, Alt-F1 for console, Alt-F2 -> Alt-F8 for virtual
screens 1 to 7.

Anyone interested in this code should e-mail me for a copy. Or given
sufficient interest, I'll post.
