i tested an indigo2 with scsi2sd (version 6) running both 5.3 and 6.5 earlier this year (posted on nekochan, didn't bother saving any of the results since I thought they would be online, sigh...), but the scsi2sd worked very nice with 5.3, I wasn't really able to tell the difference from the old drive and the SD card. If the Indigo stays on 5.3 the scsi2sd might be just fine.

IRIX 6.5 ran very sluggish on scsi2sd, I don't recommend it for 6.5 just yet. I noticed the most recent updates to scsi2sd made some write speed improvments, so I just might give it another spin before the end of this year and see how it goes.
