The T30 has a Radeon video card IIRC.  "man radeon" suggests the 
CloneMode, CloneHsync, and CloneVRefresh options in XF86Config may be 
useful.  And if you really need to display video on the external 
monitor with -vo xv instead of -vo x11, look at the OverlayOnCRTC2 
XF86Config option.  I can't test any of these things out because my 
A22p has a Rage128 video card, but read the man page and try the 
CloneMode setting and see what happens.
