Bug in booting OS/2 (fixed Warp)

I found out a bug in GRUB version 0.90-1mdk and later that didn't exist
in 0.5.96-1mdk. I don't know its nature but I see how it appears when I try to
chainload OS/2 mbr with GRUB. My OS/2 (Warp, fixed) system bootable partition
is situated above 8 Gigs. It can be loaded with native bootloader that is
located in /boot/chain.os2 (1st menu choice). Also it is possible to call OS/2
bootsector with GRUB command chainloader +1 (1st menu choice).
If I use GRUB 0.5.96-1mdk for these both types of loading OS/2 everithing
is ok. If I use GRUB 0.90-1 for this -- OS/2 is loaded but not up to the end.
Trap 000D occurs (probably after initializing MWDD.SYS)! Although OS/2
successfully loads directly or via old GRUB version.
Please, try to fix it. I'm sending you my files if you are interested
in fixing it. I can help in testing.
