 You want:
 (hd0)   /dev/rld0d

 Because you're not accessing SCSI disks (and some LSI megaraid have PATA
 or SATA drives), but a virtual drive presented by the firmware adapter.
 translating requests to SCSI commands, to then decode these SCSI commands
 and translate them to the LSI firmware interface would just be a waste
 of CPU cycle (and could eventually lead to less efficient usage of the
 LSI capabilities). RAID volumes from others hardware RAID adapters shows
 up as ld too.
 
 grub should be fixed.
