gdbserver is specifically for remote debugging of userspace programs
on Unix-like (or, now, Windows-like) systems.

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.
