Yes, I'm use reiserfs in 2.6.1 with laptop_mode patch. It works fine for me, I use cpudyn daemon to let spin download harddisk. In cpudyn.conf
I changed TIMEOUT from 120 to 10. When i reading email/web, the harddisk can spin down for very long time (>3min). 

So you can try cpudynd.

# TIMEOUT=120
TIMEOUT=10

# 
# Specified disks to spindown (comma separated devices)
#

# DISKS=/dev/hda,/dev/hdb
DISKS=/dev/hda

For now, I switch to 2.6.1-mm2, it looks fine, not need any patch.

$mount
/dev/hda13 on / type ext3 (rw,noatime,errors=remount-ro,commit=600)
proc on /proc type proc (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
/dev/vg00/opt on /opt type reiserfs (rw,noatime,commit=600)
/dev/vg00/hugang on /home/hugang type reiserfs (rw,noatime,commit=600)
/dev/vg00/scm on /scm type reiserfs (rw,noatime,commit=600)
/dev/vg00/build on /build type reiserfs (rw,noatime,commit=600)
none on /sys type sysfs (rw)
