Comment 5 for bug 346586

file attached as requested.

I think I know the keycodes and I think they are the same as keycodes in the driver for ms2141. I do not know how to extract them with wistron button, but acerhk has got some nice debugging switches, so dmesg says:

I pressed wifi button:
[16913.628291] acerhk: received key code 0x30
[16913.628305] acerhk: translated acer key code 0x30 to key name 0x8
[16913.628526] acerhk: wbutton2 = 0x9610
[16913.628533] acerhk: translated acer key name 0x8 to input key 0x93
mail button
[16861.628297] acerhk: received key code 0x31
[16861.628313] acerhk: translated acer key code 0x31 to key name 0x7
[16861.628322] acerhk: translated acer key name 0x7 to input key 0x9b
webbrowser button
[16862.228296] acerhk: received key code 0x36
[16862.228310] acerhk: translated acer key code 0x36 to key name 0x6
[16862.228319] acerhk: translated acer key name 0x6 to input key 0x96
programmable button 1
[16862.828295] acerhk: received key code 0x11
[16862.828310] acerhk: translated acer key code 0x11 to key name 0x3
[16862.828319] acerhk: translated acer key name 0x3 to input key 0x94
programmable button 2
[16863.228298] acerhk: received key code 0x12
[16863.228313] acerhk: translated acer key code 0x12 to key name 0x4
[16863.228321] acerhk: translated acer key name 0x4 to input key 0x95

I have only 5 buttons (named KEY_PROG1,KEY_PROG2, KEY_MAIL,KEY_WWW and unname KE_WIFI in the source code) on my laptop (I lack the audio panel that ms2141 has got), but otherwise it corresponds to keycodes for ms2141:

static struct key_entry keymap_wistron_ms2141[] __initdata = {
 { KE_KEY, 0x11, {KEY_PROG1} },
 { KE_KEY, 0x12, {KEY_PROG2} },
 { KE_WIFI, 0x30 },
 { KE_KEY, 0x22, {KEY_REWIND} },
 { KE_KEY, 0x23, {KEY_FORWARD} },
 { KE_KEY, 0x24, {KEY_PLAYPAUSE} },
 { KE_KEY, 0x25, {KEY_STOPCD} },
 { KE_KEY, 0x31, {KEY_MAIL} },
 { KE_KEY, 0x36, {KEY_WWW} },
 { KE_END, 0 }
};

Hope this helps and thanks for your effort, that is really great.
