[ltp] T23 running Kubuntu 7.04 - problems with Savage Direct Rendering (and USB)

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
correct number.

The key options in the xorg.conf are:

Section "Module"
        Load    "i2c"
        Load    "bitmap"
        Load    "ddc"
        Load    "dri"
        Load    "extmod"
        Load    "freetype"
        Load    "glx"
        Load    "int10"
        Load    "vbe"
EndSection

Section "Device"
        Identifier      "S3 Inc. SuperSavage IX/C SDR"
        Driver          "savage"
        BusID           "PCI:1:0:0"
#       Option          "DPMS"
#       Option          "ShadowStatus"
#       Option          "SWcursor" "True"
#       Option          "DmaMode" "None"
#       Option          "ForcePCImode"
#       Option          "BusType" "PCI"
EndSection

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?
