This is an mga driver bug, you can work around by adding Option "XaaNoScreenToScreenCopy" to Section "Device" in your XF86Config, though that makes things a bit slow.
Please attach your XFree86 config, log file, and /var/log/messages as individual uncompressed file attachments using the link below. Also the output of: lspci -vvn TIA
Please download and test the following driver: Rename your existing driver /usr/X11R6/lib/modules/drivers/mga_drv.o to mga_drv.o.orig first, then put the new one in place. Then edit your config file, and remove any options that disable acceleration, etc. ftp://people.redhat.com/mharris/test-drivers/mga_drv.o Test it fully until you are sure it works or does not work. Once I've gotten feedback from that, I can explore the problem deeper, and try to possibly fix the root cause
Tried the above mentioned driver but Xinerama didn't kick the 2nd monitor up online? Does that driver support Xinerama?

Red Hat Linux does not support dualhead on G400. You are using Matrox's binary hallib which is unsupported by Red Hat. This issue has been resolved in rawhide, but it will be unuseable to you as you require Matrox's binary hallib which we do not support. G450 and G550 users will note the problem which affects all 3 cards is fixed in rawhide now. XFree86 build 4.2.99.2-20021217
