Maybe this will shed some light. Before the big kernel compile snafu, PDP couldn't grab frames either. Now PDP can, but Gem still can't.

I got the kernel compiled and pwcx installed. I behaves similarly, except for an added message in kern.log:
pwc decode_size = 1 pwc set_video_mode(160x120 @ 10, palette 15)
This is the output from Gem, which looks just about the same as before the new kernel and modules.
starting transfer cap: name Logitech QuickCam Pro 4000 type 1 channels 1 maxw 640 maxh 480 minw 160 minh 120
picture: brightness 31744 depth 24 palette 15
channel 0 name Webcam type 2 flags 0
setting to channel 0 buffer size 921600, frames 2, offset 0 460800
wanted format is 0x1908 setting cmcapture to 160x120 5 now trying standard palette 15 frame 0 0, format 15, width 160, height 120
GEM: pix_video: Opened video connection C vmmap 825A264 VIDIOCSYNC: Invalid argument stop transfer
Now, with block and p2s-s2p the cube is mapped with a blurry garble and intermittent fuzzy cyan dots. But this is different distortion than I was getting before, it's similiar to using p2s-s2p w/out the block object on the old kernel. The new kernel is 2.6.5 with pwc/x 0.9 beta.
I'm stumped at this point, so help of any kind would be great.

For what it's worth, I never got my logitech quickcam notebook pro working _without_
pwcx.
With it it is working fine. (except that I have to unplug it and
plug
it in again if pdp closed it/crashed. Otherwise I get a blackout every second or so. With Gem it just works.
I am using the 0.9 beta drivers.

Yep. That did the trick. The image was very garbled and it ate up
~30% of
my processor cycles, but it worked. I'm still going to try kernel compilation and pcwx, but I don't
think
that
will fix it.
