[gentoo-user] Unclaimed display?

I am looking at the lshw of a compaq desktop with pci-express and a Radeon 
X600 and see that it's VGA and secondary dispalyes are "unclaimed".  What 
does this mean?  Have I got the kernel config wrong?

In the kernel I have enabled:

Maybe. Or it comes from lshw. You could look at the lspci output to
compare.

The lspci output does not show a driver either ...

01:00.0 VGA compatible controller: ATI Technologies Inc RV380 0x3e50 [Radeon 
X600]

01:00.1 Display controller: ATI Technologies Inc RV380 [Radeon X600]

It seems the system can't find the good driver for this hardware. There
may be various reasons:
- driver not compiled/installed ;
- version of this driver failing ;
- wrong Linux kernel configuration ;
- etc.

You have to manually load/unload the drivers that you think should work
to do your own tests.

It may just be a bug of sorts?  I have tried loading and unloading all sort of 
drivers to no avail.  I get good glxgears so something must work fine.  It's 
just that this unclaimed/no driver thing confused me.

Ok, I didn't understand it works. I wouldn't worry to much, then.

It's hard to tell where the problem comes from exactly (at least for me,
I don't follow the pciutils project close enough).

If you have time to spare, you can start looking at your pci.ids file
(use locate) to check if the vendor, device, subsystem and class'ID are
known. If not, fallback to the last PCI ID Repository at
http://pciids.sourceforge.net/ . If it doesn't help you, you could ask
to the linux-pci mailing list here: http://vger.kernel.org/ .
