Nils,

I'll checkout my power consumption after I'm done with my current 
recompile of gcc. 

As for console frame buffer,

[kernel config]

#
# Graphics support
#
CONFIG_FB=y
CONFIG_FB_MODE_HELPERS=y
CONFIG_VIDEO_SELECT=y
CONFIG_FB_RADEON=y
CONFIG_FB_RADEON_I2C=y

#
# Console display driver support
#
CONFIG_VGA_CONSOLE=y
CONFIG_DUMMY_CONSOLE=y
CONFIG_FRAMEBUFFER_CONSOLE=y
CONFIG_FONT_8x8=y
CONFIG_FONT_8x16=y

[/kernel config]

I've got radeon framebuffer compiled in, and I'm using morph-sources6 
for my kernel sources.

My grub launch for the frame buffer is:

title Gentoo 2.6.11-morph6 Kernel ACPI
root (hd0,2)
kernel (hd0,2)/boot/kernel-2.6.11-morph6-acpi ro root /dev/hda3 
resume2=swap:/dev/hda2 video=radeonfb:ywrap,pmipal,1600x1200-16@60 
acpi_sleep=s3_bios


I have yet to see any issues with fgl_glxgears, but I have to admit I 
don't run it all that often ;)

Also, yes I am using Xorg.  I am on a gentoo distro, so what can I say - 
I like the bleeding edge.

I'll let you know later about power consumption after a resume.
