Radeon Video Card Support.

Hello Milton,

What I meant by tweaking the driver was editing the source code, not 
xorg.conf.

E.g.

cd /usr/ports/x11-drivers/xf86-video-ati
make patch

Edit one of the source files in work/xf86-video-ati-7.5.0/src.  It might 
be something as simple as your chipset revision  not being listed in the 
header:

<<<ROOT at unixdev.local>>> /usr/ports/x11-drivers/xf86-video-ati 1034 # 
grep -i x1900 work/xf86-video-ati-7.5.0/src/*
work/xf86-video-ati-7.5.0/src/radeon_chipset_gen.h:  { 
PCI_CHIP_R580_7243, "ATI Radeon X1900" },
work/xf86-video-ati-7.5.0/src/radeon_chipset_gen.h:  { 
PCI_CHIP_R580_7245, "ATI Radeon X1900" },
work/xf86-video-ati-7.5.0/src/radeon_chipset_gen.h:  { 
PCI_CHIP_R580_7246, "ATI Radeon X1900" },
work/xf86-video-ati-7.5.0/src/radeon_chipset_gen.h:  { 
PCI_CHIP_R580_7247, "ATI Radeon X1900" },
work/xf86-video-ati-7.5.0/src/radeon_chipset_gen.h:  { 
PCI_CHIP_R580_7248, "ATI Radeon X1900" },
work/xf86-video-ati-7.5.0/src/radeon_chipset_gen.h:  { 
PCI_CHIP_R580_7249, "ATI Radeon X1900" },
work/xf86-video-ati-7.5.0/src/radeon_chipset_gen.h:  { 
PCI_CHIP_R580_724A, "ATI Radeon X1900" },
work/xf86-video-ati-7.5.0/src/radeon_chipset_gen.h:  { 
PCI_CHIP_R580_724B, "ATI Radeon X1900" },
work/xf86-video-ati-7.5.0/src/radeon_chipset_gen.h:  { 
PCI_CHIP_R580_724C, "ATI Radeon X1900" },
work/xf86-video-ati-7.5.0/src/radeon_chipset_gen.h:  { 
PCI_CHIP_R580_724D, "ATI Radeon X1900" },
work/xf86-video-ati-7.5.0/src/radeon_chipset_gen.h:  { 
PCI_CHIP_R580_724F, "ATI Radeon X1900" },
work/xf86-video-ati-7.5.0/src/radeon_chipset_gen.h:  { 
PCI_CHIP_R580_7284, "ATI Mobility Radeon X1900" },

This is just a guess based on past experience with driver issues. Since 
very few BSD/Linux users have this card, it's possible that a simple fix 
like this was never attempted.

Cheers,

     Jason
