updates + acpi

[The MiP RvL]

Hello

I want to start using FreeBSD after using debian unstable for a year :)

So I installed FreeBSD 5.1 about 2 months ago.
I installed gaim and figured out that this version of gaim didn't support msn. So I wanted to upgrade my ports tree, but because my laptop is 300 mhz, I do not want to recompile my whole ports tree. I looked at freebsd-update but couldn't figure out how it worked. I also looked at PACKAGESITE and PACKAGEROOT, but that only grabs the latest packages instead of updating the whole ports system. (I'm missing the apt-get update/upgrade tools:) Could somebody show me how to update the ports.

Further, I want to use acpi, but it gives the following error while it tries to mount my drive:

setrootbyname failed
ffs_mountroot: can't find rootvp
Root mountfailed: 6

After that I get something like this:

Manual root filesystem specification:
   <fstype>:<device> Mount <device> using filesystem <fstype>

                     e.g. ufs:/dev/ad0s1a 
   ?                 List valid diskboot devices 
   <empty line>      Abort manual input
   mountroot>

It's not possible to mount the filesytem :(

If I disable acpi than my system will boot normally.
So has anyone encounterd this problem, and if not, 
how can I get my dmesg output to put in a bug report.

This is on a toshiba portege 3020ct.
