Subject: Patch for radeon framebuffer

The patch below has been around for ages now.
It is needed on some radeon mobility cards, because they report 0 for
their video-ram-size.
Without the patch, the radeonfb will not work.

Can you include this in the next kernel release?

Hi,
i've an ATI Radeon Mobility IGP 320.
I've tried to enable the 'radeon framebuffer' in the kernel 2.4.20 and
2.4.18, but if i boot with this kernel, i can't see.. :-( I'd like to
know if with the last unstable release of the kernel (and/or with this
patch) i can enable that option..

tnx

bye bye
