Well, my experiences are more "trial and error". The second I hosed my MBR 
with grub (setup (hd0)), the Access IBM button no longer worked in BIOS. 
It was not mission critical, but it annoyed me that certain functionality 
was no longer there. About the time when I fiddled with partition type for 
R&R, I got a number of error messages from various IBM tools.

In the end, I restored the mbr (IBM released special purpose software for 
that; check thinkwiki), and set the partition type for R&R to 0x12. Now 
everything is dandy.

/dev/sda1               1        3230    24418768+   7  HPFS/NTFS
/dev/sda2           12376       12921     4127760   12  Compaq diagnostics
/dev/sda3   *        3231        3235       37800   83  Linux

+ this grub:

title=Gentoo Linux 2.6.15-r1 (gentoo-sources) + (ibm-acpi)
root (hd0,2)
kernel /vmlinuz-2.6.15-gentoo-r1 acpi_sleep=s3_bios pci=noacpi libata.atapi_enabled=1

title=Windows XP
rootnoverify (hd0,0)
chainloader +1

title=IBM rescue and recover
rootnoverify (hd0,1)
chainloader +1

... lets me:

1) use the Access IBM button from BIOS and WinXP
2) boot into gentoo/winxp/r&r from grub
3) make rescue CDs and use R&R as can be expected.

... which is pretty much as dual-boot as can be expected.

YMMV,
