Are you sure this change is correct? AFAIK 181 always mapped to 125, not 
115 as in your table (this is in the linuxconsole CVS). In any case, read 
<http://www.usb.org/developers/data/devclass/hut1_1.pdf>, especially the 
description for keys 0x87-0x98, they relate 1:1 to the linux keycodes 
181-198 in linux/include/linux/input.h. And keep in mind that 
drivers/char/pc_keyb.c maps this keycodes again! Then again tell us how you 
would like to map the linux keycodes to AT keycodes. Or checkout the 
linuxconsole CVS (codename "ruby") from sourceforge and give us a diff for 
utils/scancodes.h.

BTW, it could even be that the reporting guy does run a setkey script for 
PS/2 keyboards, but not for USB keyboards...
