Has anyone every made a PCIe video card work with the AMCC 460EX.  I am
not sure
how to set VIDEO_IO_OFFSET.  I have an ATI FireMV 2250 PCIe x1 video
card  I  am
trying to get it working with the AMCC 460EX processor.  I have u-boot
v2009.03.  I
tried following what the sequoia does for a PCI video card

I changed the 
  
   board/amcc/canyonlands/config.mk so that TEXT_BASE is 0xFFF80000
instead of 0xFFFA0000


I then added 

#ifdef CONFIG_VIDEO
#define CONFIG_BIOSEMU			/* x86 bios emulator for vga bios */
#define CONFIG_ATI_RADEON_FB		/* use radeon framebuffer driver */
#define VIDEO_IO_OFFSET			0xe8000000 // <------------- Not sure what
this should be
#define CONFIG_SYS_ISA_IO_BASE_ADDRESS	VIDEO_IO_OFFSET
#define CONFIG_VIDEO_SW_CURSOR
#define CONFIG_VIDEO_LOGO
#define CONFIG_CFB_CONSOLE
#define CONFIG_SPLASH_SCREEN
#define CONFIG_VGA_AS_SINGLE_DEVICE
#define CONFIG_CMD_BMP
#endif

And I can see the  libatibiosemu.a is linked in. However, I cannot see
anything on a monitor.
