i don't know what you read, but 2d and 3d accel are "possible". 2d accel is
done. to an extent where it is about as accelerated as most x11 drivers are
(blits, fills accelerated, xvideo yuv->rgb + scaling accelerated, everything
else software fallback). 3d is not done as it will need a fair bit of work and
no time for that currently. the problem is when you go to a software fallback
doing transfers over the bus TO the video card are not fast.

so your information is not correct. :) but it's not a powerhouse chip. don't
think that you suddenly have some iphone killer graphics chip.

needed extra sdio to get wifi for you. without needing it for wifi, glamo
wouldnt be "needed". the glamo itself has an sd card interface. thisis now used
for the actual sd card and the old sd card interface on the cpu is used for the
wifi chip. it's a price paid for wifi on the given hardware.
