Odd. I thought I tried stock 2.2.12 and it didn't detect the 4MB VRAM in my PowerMac 7500. Now I'm not so sure. A quick diff of the kernel controlfb.c sources between 2.2.6 and 2.2.12 reveal no difference though in the VRAM bank check code though so it also seems to me that if people had this problem in 2.2.6 then 2.2.12 should also be unable to detect the full 4MB VRAM. If you're saying that the hardware should be identical then could some other software be responsible such as the OF software be perhaps different and causing this different behavior? I'd really like some confirmation now that others with 7500 don't get all 4MB VRAM detected even using stock 2.2.12. I've read postings from others that they didn't get 4MB VRAM detected but I don't think that was with 2.2.12 at that time. ** Sent via the linuxppc-dev mail list. See http://lists.linuxppc.org/
