I had some time today and tested sysinstall:
6.4-Stable:
Installing a first disk allows to create DD disks and "normal" disks.
Creating slices works as expected. Comitting changes works.
Creating labels works as expected. Commiting changes works.
Installing a second disk allows to create DD disks and "normal" disks.
Creating slices works as expected. Committing changes works.
Creating labels works as expected. Committing changes works only for DD disks.
7.1-Release-p5:
Installing a first disk allows to create DD disks and "normal" disks.
Creating slices works as expected. Committing changes works.
Creating labels works as expected. Committing changes works.
Installing a second disk allows to create DD disks and "normal" disks.
Creating slices works as expected. Committing changes works.
Creating labels works as expected. Committing changes works only for DD disks.
7.2-Stable:
Installing a first disk allows to create DD disks and "normal" disks.
Creating slices works as expected. Committing changes works.
Creating labels works as expected. Committing changes works.
Installing a second disk allows to create DD disks and "normal" disks.
Creating slices works as expected. Committing changes works.
Creating labels works as expected. Committing changes works only for DD disks.
8.0-Head:
Installing a first disk allows to create DD disks and "normal" disks.
Creating slices works as expected. Committing changes works.
Creating labels works as expected. Committing changes works.
Installing a second disk allows to create DD disks and "normal" disks.
Creating slices works as expected. Committing changes works.
Creating labels works as expected. Committing changes works only for DD disks.
It is impossible to install a second disk with sysinstall. Partitioning the second disk works, but labeling it doesn't. As soon as you are committing changes only the error message "There where errors comitting labels to /dev/ad1" is displayed. I can not tell what exactly sysinstall confused.
Trying the same with fdisk/disklabel works. But the boot-label has to start at offset 0 if you'd like the bootloader find the label to boot from. At the moment: there is something seriously broken within FreeBSD-8.0-HEAD!

geom itself seems to be broken (at least the docs). It isn't helpful to just print out "geom list help" for command "geom list" if something isn't what geom expected. geom just prints nothing for any disk in the system regardless of being DD or not:
yum# geom part list
yum# geom label list
yum#
