I have MSI GE600 notebook with 1024 GDDR VRAM (source http://www.msi.com/product/nb/GE600.htm … ification). Unfortunately Arch detects only 256mb:
[piotrek@piotrek ~]$ sudo lspci -v -s 01:00.0
01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Madison [Mobility Radeon HD 5000 Series] (prog-if 00 [VGA controller])

Is there anything I can do so Arch would detect 1024mb instead of 256mb? Thanks in advance for Your kind help.

That lspci only sees 256mb is irrelevant, the component that matters - the graphics driver - *does* see 1024mb.
This lspci output only means that your GPU has 256MB + 128KB of some memory or registers mapped into CPU physical address space. Running dmesg |grep radeon will likely reveal what the radeon driver thinks about VRAM of this GPU.
Thanks both of you!
