Issues with WAPBL and Apple UFS partition

[Matthieu Lalonde <matth+netbsd%mlalonde.net@localhost>]

Hello, back in RC1 I tried enabling WAPBL on some Apple UFS partitions  
not knowing that it was incompatible. Sadly this messed up the  
partition and now I can't mount it anymore and get an "incorrect  
superblock" error. With a dd image of the disk, I tried switching the  
partition type from "Apple UFS" to 4.2BSD in the disklabel. The  
partition now mounts properly, however a lot of files are missing.  
Running fsck_ffs (with -a) didn't help either. df -h still reports the  
"old" (proper) disk usage and running du -sh reported a bunch of "file  
does not exist" error before it KP'ed the machine. Anyhow, I'd really  
like to revert what ever WAPBL did to my partition to recover the  
data. Any thoughts on this?

Thanks a lot,
Matth
