 Actually, everyone suggesting some way of doing it should also come with a 
way how to implement it :). Unless someone knows how to globally override the 
cursor ( XRecolorCursor() is the only way I've found; I'm not sure if 
changing the 'cursor' font is the best idea ), we simply can't have a 
busy-cursor, because we cannot place a hidden window under the cursor, it 
would be stealing the mouseclicks.
 But we could probably instead use a little borderless window with some icon 
or pixmap placed next to the cursor ( or maybe after starting 5 apps at the 
same time having a chain of 5 icons chasing the cursor on the desktop :))  ). 
This one shouldn't be that difficult and the result is almost the same, so I 
vote for this one.

 P.S. : Now that I've implemented startup notification even for apps started 
from konsole, I can confirm that the taskbar entries or an applet aren't 
simply good enough as the default. My taskbar is sometimes a bit crowded, so 
the startup entry is too small to notice ( moreover I have KTimemon running, 
so I'm kind of ignoring most of the activity in the bottom right corner of my 
desktop ). The startup notification simply has to be really visible by 
default, that's why I listed little splashscreens among the possibilities.
