(Mark sent his aux/vga output under separate cover.
I'm replying to 9fans just so it's in the archives.)

	term% aux/vga -p
	vga->attr: vid=0x15AD
	vga->attr: did=0x0405
	[...]
	vmware Depth         00000018
	vmware Bpp           00000020
	vmware PseudoColor   00000000
	vmware RedMask       00ff0000
	vmware GreenMask     0000ff00
	vmware BlueMask      000000ff

Are you sure your X server is running at 16bpp?
VMware looks convinced that you're at 24/32bpp
(meaning 24 bits of actual data but 32 bits of
space per pixel).

The clarity of the register contents is certainly
a refreshing change from typical VGAs.
