 |If you go with Accelx you will lose dma to dma PCI transfer which currently
 |fxtv exploits very nicely . That aside there is nothing in the bt848
 |driver which should interfere with your X server, i.e., there are no
 |X servers hook .

One other (albeit much less significant) piece you'll lose by moving over
to AccelX: In addition to the DGA extension, which Amancio mentioned,
AccelX also doesn't support the XFree86 VidMode extension.

So fxtv won't do on-the-fly video mode switching and viewport setting so
that full screen video really is "full screen".  You'll have to manually
flip modes down/up to 640x480 with the X mode hot keys (assuming AccelX
supports this), and move your cursor around to scroll the desktop and get
the video window centered on your screen.
