Workarounds for advanced RAID features in GRUB Legacy?

I'm a long-time LILO (both loaders have their merits) and non-RAID user, but have recently been fiddling with Linux Software RAID (mdadm) and GRUB Legacy configurations (as it's all that is offered with Debian testing and Knoppix by default). I've made progress and understand more than I did when I started. However, there were some problem areas. I've checked the manual, FAQ, Bugs for GRUB Legacy and the archives of this mailing list. I found a few things but they apply to RAID1 only if I understand correctly (disable raid autodetect and manually specify md, or install grub on both discs). I was wondering if there were any other known workarounds or patches for GRUB Legacy, from the ugly or tedious to the not-so-bad techniques, any and all. :-) Also thrown into the mix is WinXP. Currently storing GRUB on floppy, and manually entering config on each boot, to help me learn.

Specific areas:

* RAID 1, RAID 10, RAID5
* Partitionable RAID devices
* Picking the most up-to-date drive

Right now the cleanest option seems to be to simply put a separate ext2 partition at the beginning of each disc, have a kernel and initrd there to handle the RAID setup, and install grub multiple times, and update everything manually. But I have SATA discs, which are treated like SCSI discs, and thus have a 16 partition limit instead of the much higher IDE limit. I want to install a few different instances of Linux distributions, as well as other operating systems. And the appropriate swap partitions and data partitions. The only feasible way is to utilize partitionable RAID arrays to minimize the primary and logical partitions used as I'm pretty close to the limit and have hit it with some configurations.
