Had the same problem with the Jaunty release, and it seems that it hasn't yet been fixed in karmic daily releases.

I'm currently using jaunty(9.04) since it worked changing the drivers to fglrx. My guess is that this is related to all the AGP problems with the ati driver, but IANAD, so I can't be sure. My card is a sapphire radeon 3850 512 MB agp version, which AFAIK is a pci-express card with a agp converter, which might be useful to know.

I'll attach dmesg, lshw and lspci -vvv output from my current 9.04, if outputs from 9.10 is requested I guess I can get those too.

What's happening:
1. booting up.
2. Desktop loads.
3. black screen with a cursor on.
4. change to vt1 (alt+f1), checking if the machine responds to input, this works.
5. change back to X (alt+f7).
6. machine locks up, doesn't respond to any input at all.
