Well euhm.. that was not enough :( mounting goes ok now but i get another 
panic:

panic: pool_get: biopl: page empty

	pool_get + 0x251   (i386)
	getiobf1
	getiobuf
	lfs_newbuf
	lfs_initseg
	lfs_seglock
	lfs_valloc
	ufs_makeinode
....
	lfs_create
....

Running with DIAGNOSTIC+DEBUG+LOCKDEBUG, the kernel immediately crashes 
when reading when it starts syslogd:

pool_get: bufpl: curpage NULL, nitems 7
panic: pool_get: nitems inconsistent

trace:
	pool_get +0x1a5 (i386)
	getnewbuf
	getblk
	bio_doread
	bread
	ffs_vget
	ufs_lookup
	VOP_LOOKUP
	lookup
	namei
	sys_access
	...

So somthing is definatively wrong in the pool code :-/ also the `bp->b_vp = 
NULL;' would help on other places.

Happy hacking :)
