[Bug 485033] [NEW] Karmic boot scripts starting kdm twice during bootup

kUbuntu-9.10 64-bit, current updates

What I expect to happen: On bootup, seeing text and then greeting
screen.

What is actually happening: During bootup, either from cold or restart, it appears that kdm is being started twice. It starts once before the video driver is loaded, producing an error screen saying the fonts aren't loaded, and the "low resolution" mode screen. Escaping out of these screens returns to the text, and then the regular greeter screen appears normally. 
There is another related problem, in that the "rescue mode" is unusuable. Booting into rescue mode produces the menu. which is immediately overwritten with bootup text. Pressing Enter repeatedly produces an alternation between the "root at machine" prompt and the "Machine Login:" prompt, making it impossible to use the console.
I have disabled all kernel options such as vga= and splash, this does not help.
I have also discovered that after a "normal" boot, the usual bootup text and login prompt appears on CTRL-ALT-F1, F2 thru F6 are normal (login prompt only), on CTRL-ALT-F7 there is a second set of boot text, and the graphical screen is on CTRL-ALT-F8.
The problem does not appear to be with kdm, X or the NVIDIA drivers themselves, but with a script that is starting them twice.
This might also be a security problem, if two separate graphical logins are being started.
