you can use GNU development/debugging tools with JTAG, which gives you source level debugging
the hardware you need is a JTAG interface and i've noticed that all GNU/linux world recommends nothing but the BDI2000 for two main reasons:
1- it speaks the "gdb" protocol over the ethernet
2- it's capable of handling virtual addresses which is required for debugging MMU-capable machines
this conclusion i've got from the following posts:

and the JTAG interface you need is something like this:

correct me please if i miss understand anypoint
well, i'm about to start an embedded project also and i've choosen arm also .. it's cheap .. but at last your choice depends on your project's goals and aims at the first point
hope this helps

Raseel,
You were right. But I need info on hardware tools also.
Let me explain the scenario. I have a P4 machine with Redhat 9. And I have
an ARM based SBC (I am going to buy one). Now how do you debug your kernel
that you got onto a board ? What hardware and software tools are needed? How
do you guys manage these?
okay .. thanks for clarification ..

Though linux has been ported onto ARM9, I would like to get an ARM SBC and
do the porting myself. That helps learning the kernel. right? I am
particular about ARM because I found it to be cheap. Suggest me if there is
anything that is cheaper.
