I noticed that one when looking at newer IOS's not too long ago.  I 
assumed it was only released "for" a specific version of the 3550-24 
because that's the only model left of the 3550 family that's not reached 
EOL.  I saw that it would boot on a 3550-48, but didn't go any further 
with it than watching it boot.  What goes wrong with it?

Have you looked at the difference in RAM usage between 12.1EA and 12.2SE?
I suppose most of the RAM on a 3550 doesn't get used / won't get used...so 
15MB or 20MB free vs 40MB free really doesn't matter.
