Here's my first contribution to the linux kernel : http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=d023e49118b9c93bbab9aaf798b25f78f1a5803c.
It fixes the ACPI which had been blacklisted on P4B266 mainboards, and will allow my old machine to suspend in 2.6.31, hopefully.
Does it make me a kernel hacker ? Certainly not. But glad to be somehow part of that history ;)
