So, using the patch from my last mail, I created a btrfs, but was
unable to mount it...

[root@canola btrfs]# getconf PAGESIZE
16384

[root@canola btrfs]# mkfs.btrfs -E sectorsize=16384 /dev/cciss/c2d1
found device 1 on /dev/cciss/c2d1
lowest devid now 1
found Btrfs on /dev/cciss/c2d1 with 1 devices
opening /dev/cciss/c2d1 devid 1 fd 5
alloc chunk size 8388608 from dev 1
alloc chunk size 8388608 from dev 1
fs created on /dev/cciss/c2d1 nodesize 16384 leafsize 16384
sectorsize 16384 bytes 73372631040

[root@canola btrfs]# mount -t btrfs /dev/cciss/c2d1 /mnt/btrfs
mount: /dev/cciss/c2d1: can't read superblock

And from /var/log/messages:

Mar 31 16:50:23 canola kernel: btrfs: cciss/c2d1 checksum verify
failed on 16384 wanted A76CDD59 found 4A0E371 from_this_trans 0
Mar 31 16:50:23 canola kernel: btrfs: valid FS not found on cciss/c2d1
Mar 31 16:50:23 canola kernel: btrfs: open_ctree failed

Any hints?
