Actually, only one of the two patches appears to be necessary; the Intel
developer is in China, and should be waking up around now.  The second
patch will force higher bandwidth than necessary operation (taking
power).  So let's wait and see what ykzhao says in response to the test
that Dick Marinus did.

Several other items I forgot to mention in the original report:
   1) I reproduced this bug on Fedora Beta as well as after its initial discovery in Ubuntu 10.04; Fedora is in fact where the dmesg dump came from that I sent to ajax with the rom file.  Ajax has been recovering from a bike accident, so I've been reluctant to ask him to build me something on Fedora (he busted his arm and has a case of road rash, but is ok).  But Fedora fails identically as Ubuntu.
   2) It isn't clear this is really the same  bug #554569 or not, though the gross symptoms are very similar.  Ajax said that I had about the first eDP panel in captivity he had seen; the IBM x201 has been out considerably longer, and the Intel driver folks have x201's in captivity.  I therefore doubt that the x201 has an eDP panel, though do not know for sure.

The specific version of the HP 2540p I have is:

Exactly how urgent this bug will be to fix in the general population
depends on the uptake of eDP panels by the industry, still a bit hard to
predict.  I did the somewhat risky thing of getting the latest and
greatest laptop on the market :-(, and still got burned even having
checked if there were likely to be any issues with the X developers.
Oh well.  One more arrow to the very large collection already on my
back.

But it will certainly become a much bigger long term issue given 10.04
is an LTS release, even if your sample size ends up being just one
person with eDP displays today.
