I also have these symptoms on my Inspiron 1100.

When comparing X logs from a successful boot and one that came up blank,
I noticed the following difference:

< (II) intel(0): Output VGA connected
---
> (II) intel(0): Output VGA disconnected

Note that nothing was connected to the VGA output in either case.
(anybody know how to configure X so that it ignores the external monitor
connector?)

As an experiment, another time it came up blank I tried connecting an
external monitor and the login screen appeared on the external monitor
and I was able to log in!  However, there were still problems such as no
mouse pointer.

I also discovered that it is possible to (eventually) get a virtual
console on the laptop display by randomly banging on ctrl-alt-(F1-F6)
until one appears.

None of  this has anything to do with the looping/vertical lines
problem.  I still observe that as reported in the bug.
