And let me guess - two phase hotkey decoding is sufficiently weird that nobody wants to actually fix *that* code, right? (Rhetorical question, I already know the answer to that one). If that's not an option, perhaps we need a per-model quirk that patches up the tables at boot time? If we do that, we may want to re-arrange the table so the affected entries are at the front or something to help insure we don't patch the wrong entries if somebody else inserts new lines. --==_Exmh_1318801813_43181P Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Exmh version 2.5 07/13/2001 iD8DBQFOm1GVcC3lWbTT17ARAjcAAKDulcPEJhmcB47OTUZQfj9tZtjRWACfS7Bc WTN6JHAzVNRR5TXDrqMNFFk= =DzNM -----END PGP SIGNATURE----- --==_Exmh_1318801813_43181P--
