armv5tel and blackdown 1.3.1: Illegal instruction

Hello everybody,
 
I'm trying to run blackdown from j2re-1.3.1-RC1-linux-arm.tar.bz2 on an xscale pxa270. I've followed the install instructions (unarchive, set path) and then duplicated bin/armv4 and lib/armv4 into bin/armv5tel and lib/armv5tel to get rid of "Error: can't find libjava.so." problem ("uname -m" returns armv5tel instead of armv4).
But now I get an Illegal instruction each time I try to run "java" - could it be a difference between pxa270 and pxa255 (which i saw people run blackdown on) that causes this? (also saw an issue in the bugtracker about this but it was for an older version/i386)
 
Regards,
Danny
