Ah!  I'm afraid that currently dual-head with two different video cards
is not a supported configuration, currently.  XRandR 1.3 was supposed to
add support for this, but last I've heard it was delayed until XRandR
1.4.

Dual-head with a single video card driving two monitors ought to work
fine, especially if you use the open-source drivers.
