Not having much luck with RAID-Z boot

I'm trying out the new RAID-Z boot support, but I'm not having much
luck. After finally getting VMware to get the boot order right (and
not move on to PXE boot etc.) all I get is errors. See the original
thread:
http://www.nabble.com/Booting-from-ZFS-raidz-td21058594.html
I followed in the footsteps on the first poster (maybe not such a
great idea since it failed for him), even to the point of using three
disks in VMware Fusion, although that was a coincidence.
Anyway, I have a healthy "rpool" made out of three GPT partitioned
disks, as in the post. The only thing I changed was $1 to the disk
names (da2, da3, da4) and the size parameter for the freebsd-zfs
partition.
I then populated the pool with everything from my current r192914
install, and made sure that zpool.cache was up to date in /rpool/boot/
zfs (by copying the current copy there, and making sure it contained
"rpool").
All I get is "error 4 lba xxxxxxxxxxx", 30+ times, followed by the
loader starting to load the kernel, and failing with 10-15 lines of
"ZFS: i/o error - all block copies unavailable". It can't load the
kernel, manually or not. It does read loader.conf successfully though
(since vfs.root.mountfrom and vm.kmem_max etc. are set correctly).
System: FreeBSD 8.0-CURRENT (DTRACE) #4 r192914: Thu May 28 08:56:46
CEST 2009
Built with LOADER_ZFS_SUPPORT=YES in /etc/make.conf, no patches
applied (since the raidz boot patch was merged to current a few days
ago).
Any advice?
Regards,
Thomas
