That works. I haven't old i386 PC, I have modern one, but Andrew's
suggest exited me and I tried to run the RedBoot on the modern PC.

Build the redbot image for pc target

 mkdir ~/tmp/pc_rb
 cd ~/tmp/pc_rb
 ecosconfig new pc redboot
 ecosconfig import $ECOS_REPOSITORY/hal/i386/pc/current/misc/redboot_GRUB.ecm
 ecosconfig tree
 make -s

 ls -lR install/bin
 install/bin/:
 total 492
 -rwxr-xr-x 1 sg sg 495854 May  7 14:03 redboot.elf

All rights. I did insert my USB pen. Ubuntu mounts this storage to
/media/disk, and I just did copy a future `kernel' there:

Install the image

 cp install/bin/redboot.elf /media/disk
 umount /media/disk

At the end, I appended these 3 lines to my GRUB's menu

 title		RedBoot (pc target)
 root		(hd1,0)
 kernel		/redboot.elf
 
Note: `hd0' is my SATA HDD and I used the `hd1' reference to boot from
my USB memory stick. You have to set up the hd's number correctly.
Usually, it's enough to look at `dmesg' output to resolve this issue.

I rebooted my PC and saw the expected choice in the GRUB's menu. I did
choose new menu's item... and saw that the RedBoot did start. It's pity
that I haven't old i386 PC. It looks like I won't got the RedBoot's
networking on my hardware. But GRUB runs the redboot image from USB pen
without any problems.

Thanks Andrew,
