I went through the second link that you have posted.
The author there said that he has attached the attachment in the post in http://www.mail-archive.com/acpi-bug.../msg14582.html .
But the thing he has attached and the thing attached in the mail-archive.com think are not the same.(they are of different sizes ) .
And the one you have posted is of size 5.9kb.
I would go with your's and see. unfortunately I don't have my laptop with me right now.
I would post back as soon as I have finished the process.

They are the same, they just use different compression formats. The tarball from mail-archive.com uses a bzip2 compression, the one attached in ubuntu-forums has a gzip compression, and the archive I posted uses zip (I used zip because this forum won't let me upload gzip or bzip2 archives/tarballs).

hehehe
thank you :-)

Since ubuntu 8.10 is out what I am thinking is that I do a complete reinstall of the "32bit" os.
can I still use the same patch?

>can I still use the same patch?
Nope. The mempat binary is compiled for x86-64, and oddly enough, I can't find the source for it anywhere.

Thank you, I shall then install ubuntu 8.10 64 bit.
