It is (I've done it), but it can be tricky.  I did it a while back
with a 2.4 kernel on a 8245-based board.  If I remember correctly the
trick was to set a breakpoint inside a kernel call (I used an ioctl)
that came from your userspace app and then map the userspace
executable to start at address 0x0.  After that you are able to set
breakpoints in the user-space app and do whatever you need.  After
doing it I remember seeing a description of basically the same steps
online somewhere.
