I suspected that - just tried the vesa driver on the X1 w/ the same 
effects - XFree86  hangs w/ both panels attached and runs fine w/ one.

In the mean time where should I place efforts for a work around?  Xfree 
snapshots?  2.6 kernel?  Im using the Intel 7505 chipset which requires 
agp_try_unsupported=1 on the 2.4.22 kernel and I was curious if the 
problem was AGP related.  Or is it(gasp) ATI custom drivers w/ no Xinerama?
