msk dev problem with acpi

[William Grzybowski]

Hi all,

Well, I am a university student in the second year with a reasonable
knowledge in C and would like to help in anyway the FreeBSD project,
specially acpi.
I don't know much about it at all but could be a nice opportunity to learn
about things which I always liked, starting with small stuff, of course, and
help the community.
So, would be nice to know your opinion about it, if it sounds
reasonable/possible, anything...

Thanks :)

Bye.
