Lei,

this will be up to experiments not to specification from Philips I
guess. There will be no tested devices running at or above 150C but I
am very sure they run for a while. 
You will not have the chance to reprogram the Flash at least I would
not recommend to do that at 150C and these high temperatures are used
for stress test, aging the device with a factor of ?? (could be 10,
100 or more). 
I was present when this subject was discussed at an Embedded
Conference and those guys had used the LPC2106 and the LPC2129 for
similar tests and found the running several hours above 180C. If I
remember correctly they quit above 200C. You might have problems with
a desintegrating board at these temperatures anyhow. Am I correct that
you are talking hours / days at the max of operating life time or do
you expect months / years? If it is months, I doubt you will find a
lot of devices for these temp ranges.
