You need the ruby kernel patch set to support multiple VTs.
http://linuxconsole.sourceforge.net/
http://linuxconsole.bkbits.net/

There are also patches for supporting multiple video cards/users from
X but I don't know where they are. Ask on the x.org list or James will
know.

I'm not sure how multiple keyboards are handled in ruby. For Xegl I am
using the new evdev interface.
http://www.frogmouth.net/hid-doco/c537.html for examples.

Dealing with multiple video cards is very challenging especially
without the hardware documentation.

For a different project you might want to try implementing the EGL
interface on a 3D card. Documentation for ATI Rage128 and Mach64 (no
one is working on these) is available so if you could get your hands
on a PCI version (about $30) of one of those you'd be set. You want a
PCI version for target debug, then you run X and your debugger on the
Nvidia AGP card.

Implementing EGL is more narrow in scope and should be easier to do.
EGL forms the basis of Xegl which is the new 3D accelerated X server.
