Name of PS3 storage device is renamed to '/dev/ps3daN' from '/dev/sdN'
on 2.6.23 kernel.
So, name of root device is changed to '/dev/ps3da2'.
Did you change name of root device in 'kboot.conf'?
You must change name of root device in 'kboot.conf' as follows :
| ydl_htlb ='/dev/sda1:/vmlinux-2.6.16_HTLB initrd=/dev/sda1:/initrd-2.6.16_HTLB.img \
| root=/dev/ps3da2 init=/sbin/init video=ps3fb:mode:3 rhgb'
Regards.
