gdbserver is specifically for remote debugging of userspace

You need a "stub" which translates from the JTAG
device's interface to
GDB's remote protocol. You'll have to check with your tools
vendor or
JTAG vendor to see whether one exists; usually these are
proprietary
applications, since vendors are not willing to publish specs
for their
JTAG devices. I know CodeSourcery's tools support a bunch
of JTAG
units, but none which are PCI cards.
