Hi Peter,
First, usbkbd.c has very probably zero business with this - the mappings are being done in hid-input.c, usbkdb.c is only for embedded/debugging cases, and is almost never used on modern systems (see the corresponding Kconfig help text).

For USB, we have Hid Usage Pages, which define this to be KEY_HOMEPAGE. There is no such specification for PS/2 though, so what Hans is proposing is to make it consistent with behavior of USB HID devices, which I agree with.
