	Hmm...  I think it does.  For example, my Diamond Stealth 64 PCI
has 2MB of Video RAM.  That means it can display 16.7 million color
palettes (2 to the 24th power = 16,777,216 colors), or 24-bits per pixel,
at 800x600 resolutions, or a total of 480,000 pixels on-screen.  So 24-bits
per pixel times 480,000 pixels is 11,520,000 bits, divided by 8 yields
1,440,000 bytes of video RAM required. But the Diamond Stealth 64's VRAM
can be expanded to 4MB (I have a feeling it would cost me an arm and a leg
to do this so I don't think I will anytime soon...  grin) to display 24-bit
color at 1280x1024 resolutions, for a total of 1,310,720 pixels on screen,
which is over twice the number of pixels on-screen than the 800x600
modes.  This means 1,310,720 x 24 bits per pixel divided by 8 to yield
3,932,160 bytes, which is more than what my present amount of Video RAM
can handle.

	I think the ET4000-w32p cards have a 32-bit chip on-board, yes?
I have seen them with 2MB of RAM on-board, so that means a maximum palette
(16.7 million true-color mode) at 800x600 resolutions.
