[ltp] T23 running Kubuntu 7.04 - problems with Savage Direct Rendering

-----BEGIN PGP SIGNED MESSAGE-----
I recently installed the latest Kubuntu 7.04 (linux 2.6.20, x.org 7.2,
kde/kdm 3.5.6) on my T23 (2647-4MG) and I have a couple of problems. The
distro wiki and forums proved ineffective.
First the short thing - USB doesn't get powered up after suspend or
hibernation. The modules are all loaded normally. What should I do?
The problem is that I don't have direct rendering as I had before (in
Kubuntu 6.10). Moreover I carelessly lost the working xorg.conf in the
process of reinstallation.
There are the key info about my configuration. BTW - Can anyone tell me
where does it say I have 16MB video RAM? I always thought that is the
'sudo lspci -vvs 01:00'

The key options in the xorg.conf are:
Identifier "S3 Inc. SuperSavage IX/C SDR"
# Option "DPMS"
# Option "ShadowStatus"
# Option "SWcursor" "True"
# Option "DmaMode" "None"
# Option "ForcePCImode"
# Option "BusType" "PCI"
The commented options were suggested by a guy on Polish Ubuntu forum
(apart from DPMS that I added myself). Direct rendering doesn't work
either with or without them. (Some of them should be default anyway.)
I tried with 'savagefb' driver, but X doesn't start. With 'vesa' driver
it starts, also without direct rendering.
The graphics related modules loaded are: agpgart, intel_agp, drm, savage.
I may be clueless, but can anyone tell what am I missing here?
