Christopher Penalver, thank you for your continued interest in sorting
out this problem.
Following your instructions, I have installed kernel 3.12.0-031200rc6.
So far I am unable to make the stripey / herringbone pattern show up
(neither on reboot nor on cold boot). In contrast I booted twice with
the current production kernel 3.11 and both times got the stripey
herringbone pattern.
This sounds good and I guess it is, so I will change the tags to fixed
upstream as per your instructions, but I will continue to test booting
(sorry to sound pessimistic).
One thing I notice with the new kernel is the following behaviour:
- after the bios splash screen goes away, I see a purple ("aubergine") colour
to the screen, with no other detail. this lasts for a few seconds.
- then I see this message in white text at the top left of the screen (also
repeated in /var/log/syslog)
TIMER: vector=0x30 apic1=0 pin1=0 apic2=-1 pin2=-1
MP-BIOS bug: 8254 timer not connected to IO-APIC
- after two - three seconds, the screen changes to the purple background
with the Ubuntu logo and the orange/white dot progression and boot
proceeds as normal.
In contrast, what I saw with the previous kernel was the same purple
coloured screen with no other detail, followed by a brief flash and then
the stripey / herringbone pattern; at which point I waited for the drum
roll, closed the lid, let the laptop suspend, opened the lid, and all
was fine.
I am wondering if it's possible that the appearance of the two error
messages above somehow creates conditions where the screen remains in a
reasonable state. Anyway, as I say I will continue testing.
Thank you very much.

Title:
1002:5975 [Dell Inspiron 1501] vertical coloured lines / herringbone
pattern on startup
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
This problem occurs intermittently on my Dell Inspiron 1501 laptop.
For instance, on booting the Saucy beta 2 release from USB stick; or
today, booting the installed 13.10 beta 2 with all updates current.
But not always. The screen is 100% illegible when this happens.
WORKAROUND: Wait for the screen to blank on power save; when it is
reactivated, the display is fine. Or if screen blanking is not
engaged, close the lid, wait, and open it again.
