LinuxQuestions.org - FreeBSD installation causes "Partition # does not end on cylinder boundary."

I wanted to upgrade FreeBSD on my laptop from 8.1 to 8.2.
At the same time I took the opportunity to enlarge some partitions on my laptop.
And fix the "Partition # does not end on cylinder boundary." errors I have been experiencing for several months.
My laptop runs multiple OS's; WinXP, FreeBSD, Slackware, Ubuntu, Suse.

The basic procedure I followed was:

Backup each Linux OS to an external drive.
( I only backed up the Linux's and not Windows or FreeBSD.
Because Windows was on partition #1 and was only going to be enlarged.
And the FreeBSD was going to be a complete reinstall.)
Use Slackware installation DVD to repartition and format the laptop's drive.
( Keeping all OS's on the same numbered partition as before the change.)
Reinstall each Linux OS.
Install FreeBSD 8.2.

Everything went mostly very smooth.
I did have a few minutes of terror when Windows XP would not boot.
But then I realized I had it's newly resized partition type set to 83 (linux); instead of 7 (HPFS/NTFS). Oops :D
And I still have to determine why Ubuntu and Suse aren't loading their kernels.
But I hardly ever use those two; and they use initrd; while the Slackware does not.
And the Slackware booted without any issue.

So after restoring the three Linux's and fixing Windows; and before install FreeBSD 8.2.
My laptop's disk looked like this:
(From Slackware prompt.)

But after installing FreeBSD 8.2.

What could I have done wrong ?
Is it simply because I created the FreeBSD partition/slice using Linux's fdisk ?

Thanks;
