I try this out on 2.4.20 with other patching.
My machine is an Asus super 7 (K6 500) with PCI & AGP voodoo banshees.
BIOS requires boot VGA to be PCI.

Both heads are init by driver, BIOS head is head 0. Head 1 is
misdetected to be only 4096KB video memory, should be 16384KB as is head
0. After remapping a virtual console to fb/1, I have no video signal on
either head now until I fbset each to depth 16.

Tested system with mplayer output to tdfxfb driver. Video only on fb/0,
but with mplayer on console on fb/1 both heads are responsive.

Unfortunately I tried mplayer with DirectFB, it crashes unable to init,
and (it's enabled with xfs patch) I get into gdb. And my keventd kernel
thread is zombie. sysrq kessages appear on (current) fb console, but
consoles otherwise unresponsive.

I try mplayer with tdfxfb again. No complaints but also no image on fb/0
