my x1900xt's bios

Kernel 2.6.35-rc3, Xorg-Server 1.8.1, xf86-video-ati 6.13.0
For some weird reason my system consumes ~15W more when I set the power_profile
to auto, compared to all other power-profiles (low, default and high all
consume the same amount of power). I measured this with a powermeter.
"cat /debug/dri/0/radeon_pm_info" always says: 
default engine clock: 500000 kHz
current engine clock: 499500 kHz
default memory clock: 600000 kHz
current memory clock: 594000 kHz
PCIE lanes: 0
No matter which power_profile I select.
My card is a ATi X1900XT. dileX_ on #radeon suggested that I attach my
video-card bios, so I'll do that.
