X won't start: xf86MapVidMem: Could not mmap framebuffer (0x000a0000,0x20000) (Invalid argument)
Note: X always worked with grsecurity kernel provided that I disabled mmprotect (and other protections) on /etc/X11/X . I have done that. I am using a config based on a config that worked in the recent past.
kernel: 2.6.36.3-grsec
hardware: toshiba satellite l505d-gs6000
Processor: dual core AMD
Videocard: radeon (using the standard opensource drivers)
Things I allready tried:
echo options radeon modeset=0 > /etc/modprobe.d/radeon-kms.conf
(and updated the initramfs's, including the grsecurity one)
I tried with pnpbios turned on and off.
Error message:

Fatal server error:
xf86MapVidMem: Could not mmap framebuffer (0x000a0000,0x20000) (Invalid argument)
Also, at boot up, the first thing I get onscreen after grub inits is:
[ 0.598030] pci_root PNP0A08:00: address space collision: host bridge window [mem 0x000cc000-0x000cffff] conflicts with Video ROM [mem 0x000cc000-0x000cedff]

Please help me. I need X to work as I do 3d work.
