Re: "assumed" graphic card memory

May be using we can use the internals of lspci and pciutils.
So that we can calculate the VGA memory on the fly.

Use the PCI variant ;-).

Obviously. The correct PCI path would need to be found first.

(I used "lspci|grep VGA", hehe.)

Default to 64MB on those systems.

Ok. Guess it's rubbish then, too bad.
Oh well.

Promising!

But perhaps an easier approach would be to fix every Linux driver
to report the correct number in sysfs. I'm pretty sure each driver
knows how much RAM is on the card already, so it should be trivial..
