loadkeys reports "killkey called with bad index"

[Tom Metro]

Binary package hint: kbd

On Ubuntu 9.04 using kbd 1.14.1-4ubuntu4 I used showkey (with no options) to find the keycode for a couple of keys on my Acer Aspire 8930G notebook that had been reporting no evens in X (xev). showkey reported 435 and 434 as the keycodes. I created a keymap like:

keymaps 0-63
# map Euro key to Home
keycode 435 = Home
# map $ key to End
keycode 434 = End

and processed it with loadkeys from the console, which reported:
killkey called with bad index 435

A quick search turned up the source for a version of loadkeys.c that shows:

http://dev.laptop.org/~mstone/sources/expanded_srpms/kbd-1.12-22.fc7/kbd-1.12/src/loadkeys.y
#define NR_KEYS 256
[...]
static void
killkey(int index, int table) {
 /* roughly: addkey(index, table, K_HOLE); */

        if (index < 0 || index >= NR_KEYS)
         lkfatal0(_("killkey called with bad index %d"), index);
[...]

From what I can tell, 435 is in fact a keycode (and not one of the other things showkey can report), and is supposed to be a decimal number, so that leads me to wonder if NR_KEYS needed to be updated to reflect the current capabilities of the keyboad driver.

I'll try grabbing the proper source, increasing that limit (512?), and giving it a spin to see if it chokes elsewhere.
