The config tool now can configure multihead on multihead cards.  
I don't know if it is working with multiple separate cards 
however.

Note also that multiple card multihead combinations may or may
not work in XFree86.  It is highly dependant on the specific
hardware, the drivers used, in some cases the slot the cards are
plugged into, and what card the BIOS considers "primary".  In 
other cases it may depend on wether or not the BIOS posted each 
video card or not, and in cases where it hasn't, wether or not 
XFree86 is able to mmap the BIOS and post it manually.  On 
non-x86 this is done inside an x86 emulator and there may be 
additional problems if the BIOS doesn't like being ran in the 
emulator.

Short story is, try it and if it works, great!  If not, you're 
best off reporting multihead bugs like that to XFree86.org 
bugzilla at http://bugs.xfree86.org as each person's individual 
multihead configuration tends to be quite unique due to the 
complexity of variables involved.

Hope this helps.
