I've had good luck with my IOGear Miniview GCS 78 -- 8-port VGA, PS/2 keyboard,
PS/2 mouse.

I've used it with Win2k, WinXP, Win2003SBS, Debian GNU/Linux, Damn Small Linux,
and FreeBSD, in recent memory, and probably several more in the past.  I've also
used the GUC100KM PS/2 keyboard and mouse to USB converter successfully with
several platforms.

Sometimes I wish the KVM had sound, but what I really need to do is build a
matrix mixer/ distribution amp that sends each of eight line inputs to the other
seven outputs (e.g. no feedback loop)...

I ran into *severe* problems in the past using KVM's with older AT keyboard/
serial mouse machines.  Basically, I went through every unit available at Fry's
and returned them all.  Life only got better when I finally mothballed the
ancient hardware.  However, I do recall that IOGear worked correctly, but that I
returned it because the hot-key sequence started with Ctrl, Ctrl (Duke Nuk'em
3D's fire button).

Consider buying retail, so you can test the KVM with everything you have and
return it if you find compatibility problems and/or hot-key issues.

My KVM's hot-key sequence is Ctrl, Alt, Shift, <num>; in that order.  Thus far,
I haven't run into an conflicting application or platform.

Check the hot-key sequence of any unit before you buy.
