If the firmware for ipw2100 remain the same under 2.6.16.29 => 
2.6.17-10, you could simply copy (NOT move) the needed files in 
/lib/firmware/2.6.17-10-generic/ => /lib/firmware . Again, it may or may 
not work depending on whether the kernel module of ipw2100 has changed 
between version .16 and .17
You may want to submit a bug report to insure that the next xen kernel 
build for 2.6.17 has its firmware in  the proper location.
