uvesafb failing

I'm wanting to get my laptop to have a 1280x800 framebuffer and was looking at uvesafb for it as looking at the output from "hwinfo --framebuffer" the standard framebuffer wont support it.

From reading http://wiki.archlinux.org/index.php/Uvesafb this is what I've done:

pacman -S v86d.
Edited /etc/mkinitcpio.conf and added v86d to the HOOKS right after base.
mkinitcpio -p kernel26.
Edited /etc/modules.d/uvesafb.conf and changed the line to "options uvesafb mode_option=1280x800-16 scroll=ywrap".
Edited /boot/grub/menu.lst and removed all instances of vga=x.

Now, when I reboot I know it must be using uvesafb because it switches to a framebuffer and I'm not using "vga=" in the Grub config, but I don't think it's 1280x800 and looking at the kernel.log I'm getting this output:

I'm using Arch Linux 64bit and my graphics card is an ATI Radeon HD 3200.

Any ideas?

Re: uvesafb failing

why you don't use catalyst OR xf86-video-ati ???

Re: uvesafb failing

I am using Catalyst but I didn't realise it came with a console framebuffer?

Re: uvesafb failing

I've got the exact same problem (on two machines) using uvesafb and the proprietary ati catalyst driver (fglrx).

uvesafb: mode switch failed (eax=0x34f, err=0). Trying again with default timings.

I wonder if its even possibly to use a framebuffer with fglrx?

Do not necro-bump old threads. You are better off starting a new thread and linking to this one to let people know what you have tried.
