Multi-Disk RH config question

[Sampson Fung]

Dear All,

Currently I have 3 versions of RH installed to 4 SCSI HDD of my first 
AIC7770 card and I have a linux software raid on my second AIC7770 card.

My disk map is:

/dev/sda1       ext3    /boot
# only used to store menu.lst, each RH has its own boot sub-dir.
/dev/sda2       ext3    /tmp
/dev/sda3       swap    swap
/dev/sdb1       ext3    / (of RH80)
/dev/sdc1       FAT32   W2K
/dev/sdd1       ext3    / (of RH81wks)
/dev/sde1       ext3    / (of RH81svr)

Now, I can boot all the three RHs with entries in the 
(hd0,0)/grub/menu.lst.  Its content are:

title   RH80
        root (hd1,0)
        kernel /boot/vmlinuz ro root=/dev/sdb1
        initrd /boot/initrd.img

title   RH81wks
        root (hd3,0)
        kernel /boot/vmlinuz ro root=/dev/sdd1
        initrd /boot/initrd.img
        
title   RH81wks
        root (hdr,0)
        kernel /boot/vmlinuz ro root=/dev/sde1
        initrd /boot/initrd.img

My quest is:

Can I have menu.lst on different partitions to work in a "cascaded" mode?

That is:

In the "top level" menu.lst, I have three partition to choose with.  For 
the selected entry, it will read and use the "second level" menu.lst on 
the corresponding partition.
