I can throw a little more confusion into the pot.    :-)

I followed your link and picked up the JTAG Debug Agent from there. It
appears to be an older version of H-JTAG, also from twentyone or
Tang-ZhongGen???  On my system JTAG Debug Agent also can not recognize
an LPC2148 on an Olimex board, but it does reset the LPC2148 every
time it tries to recognize it. That is more than H-JTAG was able to
do. One big difference between the two code sets is that JTAG Debug
Agent uses the original Dale Roberts GiveIO.sys for high speed IO on
WinXP, while H-JTAG uses H-JTAG.sys for the same function. GiveIO
works very well on my WinXP system, but I am not so sure about
H-JTAG.sys since I do not have a way of independantly testing like I
do with GiveIO.

Here are my answers to your questions.
Q1.  What are your parallel port settings?
A1.  EPP port at 0x378

Q2. What LPT cable length do you use?
A2. 1 meter cable originally supplied with an EasyICE.( works great!)

Q3. Anything weird around your IDE settings?
   
A3. Does not really matter. H-JTAG displays the ID in the center of
the H-JTAG server screen. In my case, both ARM SDT2.51 and IAR
Embedded Workbench fail when the H-JTAG server indicates "UNKNOWN" in
the center of it's screen.
