as i said, ati r128 inside a powerbook (ppc),
using linux + xfree86 4.1 + dri:
	PCI:*(0:16:0) ATI Rage 128 Mobility LF rev 2, 
	Depth 16, (--) framebuffer bpp 16
	Pixel depth = 16 bits stored in 2 bytes (16 bpp pixmaps)
	Default visual is TrueColor
	RGB weight 565
	Using 6 bits per RGB (8 bit DAC)
	Using framebuffer device
	Chipset: "ATI Rage 128 Mobility LF (AGP)" (ChipID = 0x4c46)
	VideoRAM: 8192 kByte (128-bit SDR SGRAM 1:1)

no gatos, Xv is included in xf86 by default,
but the rendered video is very blurry .. Xv problem.

;-) and for my r128 ;-)

.. i just used the code from my xmame.xgl (gl video driver for xmame)

you have update callbacks for frames, slices and for page flipping.
so now, the frame/slice just updates the bufferd image
and page flipping updates the texture and swap's -> faster.

well, i use mjpeg-tool's mpeg2enc to produce SVCD compliant mpeg2 streams
so .. i was just curious if i had produced only rubbish streams
with a too high bitrate .. so, because they are VBR, i guess it's
ok. will check this on a friends DVD player.

das true .. but only using the mini linux kernel for the 64',
then it will be easier to ftp it to the latter host.
hmm .. insecure, we better use an encrypted smartcard.
