XVideo is supported on all chipsets of both families (except the XGI Volari
Z7 which lacks hardware support for video overlays). However, there
are some differences in hardware features which cause limitations.

About Merged Framebuffer support
.PP
Merged framebuffer mode is similar to dual head/Xinerama mode, but has a
few advantages which make me recommend it strongly over Xinerama. Please
see http://www.winischhofer.at/linuxsisvga.shtml for detailed
information.
Merged framebuffer mode is similar to dual head/Xinerama mode (for using two
output devices of one card at the same time), but has a few advantages which

About dual-head support

Dual head mode with or without Xinerama is fully supported, be it with one card
driving two outputs, be it two cards. Note that colordepth 8 is not supported in
