ufs_get_fs_state() needs the file system type to read the state from the 
correct place in the superblock. It takes the type from 
UFS_SB(sb)->s_flags, but that value is stored after the first call to 
ufs_get_fs_state(). The patch below moves the assignment of s_flags up, 
before the first call to ufs_get_fs_state().

The patch is against linux-2.6.23-rc6-git7, but it applies (with offset) 
to 2.6.22 and to earlier versions as well. It has been tested on the 
Solaris flavor of UFS (ufstype=sunx86) - with this change, the file 
system can be used in read-write mode.
