启用radeonfb 的framebuffer支持出错

redsonic

已将radeonfb 写入initrd 。
grub设定：

1. title openSUSE 11.1 - 2.6.30-9 -radeonfb
   
2.     root (hd0,6)
   
3.     kernel /vmlinuz-2.6.30-9-pae root=/dev/disk/by-id/ata-Maxtor_6L160P0_L409MK9G-part8 resum
   
4. e=/dev/disk/by-id/ata-Maxtor_6L160P0_L409MK9G-part6 splash=silent showopts video=radeonfb:1920x1080-24@60,mtrr:3,ywrap
   
5.     initrd /initrd-2.6.30-9-pae
   

复制代码

重启后，内核加载initrd的过程中死机，再重启，取消video=radeonfb:1920x1080-24@60,mtrr:3,ywrap 后恢复。
dmesg |grep radeonfb  显示:

1. radeonfb 0000:01:00.0: PCI INT A -> Link[LNKA] -> GSI 11 (level, low) -> IRQ 11
   
2. radeonfb 0000:01:00.0: BAR 0:[color="Red"] can't reserve mem region [0xd0000000-0xd7ffffff][/color]
   
3. radeonfb (0000:01:00.0): cannot request region 0.
   
4. radeonfb: probe of 0000:01:00.0 failed with error -16

哪位知道这是和什么东东冲突吗？
PS：没有用fglrx 驱动和radeon hd ,而是 用的radeon .
