Lpc2000

Just doing a "1-month later" check on tools used with the LPC210X.
Before, I got positive feedback about Ashling and Nohau, and some nice
words about Leon Heller's board as well as Rowley Associates.  Since the
group has grown, experiences have grown, and because it really looks
like I've got to do this, I'm asking again..

1. What are the GNU-based tools that developers use with the LPC210X,
and how do they compare?

2. (slightly OT) Does anyone use these same tools with other ARM parts
-- namely, the Sharp LH75410 and the Atmel AT91RM9200.  Are the tools
plug'n'play across all ARM7/9 cores or is there more to it than that?

Any info is appreciated..and..I APPRECIATE YOUR PATIENCE!!
