Me too, since you will get something like this:

application_1.4.5-r5_bigscreen.ipk
application_1.4.5-r5_ppc603e.ipk
application_1.4.5-r5_armv5te.ipk
application_1.4.5-r5_smallscreen.ipk

Now Marcin wants to install 'application' on his webpad and it doesn't run. Why? Because
'application_1.4.5-r5_bigscreen.ipk' secretly is ARM instead of x86.

regards,

Koen
