I'm assuming the same is true for Debian and mkinitramfs.  Things
like volumegroups work fine - the usual problem is device drivers.

Mkinitrd has --with to include specific drivers.  For instance,

mkinitrd -v --omit-scsi-modules --with=xenblk --with=xennet initrd-2.6.9-100.ELxenU.img 2.6.9-100.ELxenU

To include xen drivers for a virtual machine or

mkinitrd -v --with=megaraid ...
