Hi Greg,

You are very welcome to test fake-PAE :-)

You find the information at this link

https://help.ubuntu.com/community/Lubuntu-fake-PAE

Look at it all, then decide which way you want to go

https://help.ubuntu.com/community/grub-n-iso
or
https://help.ubuntu.com/community/InstalledSystemFakePAE
or mörgæs's way
https://help.ubuntu.com/community/PAE

If you need more details to make it work, I suggest that we exchange
information directly (for example via private email), because those
details are probably not relevant for the bug report.

I have a Thinkpad T42 with a Pentium M 1.7 GHz myself, so it will be
valuable to get test results from your x41, t41, and last but not least t40.

And in the end, we can publish your results in the list of tested CPUs
(in the wiki) and more verbose at the bug report.

Best regards
sudodus
