Hi,
I've been discussing the merits, potential implementations and failure
modes of booting from raid 4|5|6 volumes. One of the big complaints is
that bootloaders are limited when using int13h to accessing harddisks
plugged into the controller booting from, making it impossible to
assemble raid 4|5|6 array in this case.
I want to know if this is a limitation imposed on grub2, or is it smart
enough to access the disks on all controllers on the host.

GRUB 2 has ATA and SCSI support, so it may help.
