Mounting Promise RAID0 w/ Linux software RAID

Hi,
I am trying to recover data from a stripe set (RAID0) that was written
using the sort-RAID functions of a Promise UDMA-133 Fasttrak controller.
The mainboard with that controller has died, and I don't have
another one around to try to run the discs on!
I've been able to start and mount the array, but I think I'm only
getting the first stripe or something that's on the first disc.
I know the stripe size had been 64kb and there were two discs in the
array. The first disc has a proper partition table, but it's for the
full array, as would be on a Linux md device. I'm having trouble
figuring how I would even try to specify this...
Does anyone happen to have any suggestions on this one? I don't want to
have the scrap the data, or buy another piece of hardware with one of
those controllers on it!
Here's the partition tables:
Disk /dev/hdl: 122.9 GB, 122942324736 bytes
255 heads, 63 sectors/track, 14946 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/hdl1 * 1 29893 240115491 7 HPFS/NTFS
Disk /dev/hdj: 122.9 GB, 122942324736 bytes
16 heads, 63 sectors/track, 238216 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes
Disk /dev/hdj doesn't contain a valid partition table
And here's the raidtab:
raiddev /dev/md2
raid-level 0
nr-raid-disks 2
persistent-superblock 0
chunk-size 64
device /dev/hdl1
raid-disk 0
device /dev/hdj
raid-disk 1
