Having hit a similar issue (big FS, I wanted XFS, but needed to run centos 
4), I just went ahead and stuck with ext3.  My FS is 5.5TiB -- a software 
RAID0 across 2 3w-9xxx arrays.  I had no issues formatting it and have had 
no issues in testing or production with it.  So, it can be done.  Perhaps 
the bugs you're hitting are in the FC driver layer?
