[Linux-fbdev-users] intelfb 855gm memory issue

[Baard K. <ba...@in...>]

Hello

I have a Dell Inspiron 510M with Intel 855GM chip.
510M has no video memory option in bios(with the latest A09) , so agpgart
allocates 892KB video memory. In other words, I can't run at any higher
res. than 1024x768-8. 
I run 1400x1050 in Xfree86, but it seems to allocate memory on its own:

(II) I810(0): detected 892 kB stolen memory.
(II) I810(0): I830CheckAvailableMemory: 705532 kB available
(II) I810(0): Will attempt to tell the BIOS that there is 12288 kB VideoRAM

How can I make intelfb(or agpgart?) allocate more ram for higher res.? 

intelfb has an option
MODULE_PARM_DESC(vram, "System RAM to allocate to framebuffer in MiB");
but passing "video=intelfb:1024x768@60-16,mode=1024x768@60-16,vram=16,hwcursor=0"
doesn't help(intelfb says vram=0).

Any way to fix this? I don't think Dell is going to update their bios,
so that's a dead end.

I run 2.6.11.2
