Christopher, based on your question, I added NOMODESET to
/etc/default/grub definition of GRUB_CMDLINE_LINUX_DEFAULT, ran update-
grub, and rebooted.

Short answer - it no longer provides any salubrious effect.

Long answer:

The system booted into stripey / herringbone display, though there were
some pure-white patches interspersed with the herringbone pattern.

I closed the lid, waited a moment, and opened it, and the display
appeared to be in a lower resolution mode.  I logged in and checked;
sure enough, it was in 1024 X 768 rather than 1280 X 800, and I could
not select that higher resolution mode in screen settings - it was not
offered.  Also the video performance was   v e  r   y    s   l   o   w.

So I removed the NOMODESET and rebooted.  I guess today is a good day
for rebooting as I did not get the herringbone / stripey pattern on this
boot.

One other odd effect I have noticed.

If the system boots into SHM (stripey herringbone mode) and I correct it
by closing the lid and reopening it again, subsequently after screen
blanking the screen reappears in SHM.  I don't recall this behaviour in
the past.

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.
