No, the new firmware cannot be used with v2 or legacy driver.
No, you cannot mix the versions of the drivers.
No, it is not planned and the kernel maintainers won't accept this huge package anyway.
The Gentoo added driver and tool versions do not support REV3 cards. Either use the
downloadable latest versions from ftp://ftp.melware.net/ or check out the ebuild informations
at the gentoo bug tracker. Those can be found under http://bugs.gentoo.org/show_bug.cgi?id=142634
If you use Line-Interconnect within one card (e.g. across ports on 4BRI), then there is no problem.
But if you have more cards, then the clock source may not be synchronized and causes bit errors
(no problem for voice, but fax,modem,data connections may be faulty). If all cards (BRI),
or all first ports of 4BRI cards are in TE-mode and on one clock source like the public switch, then
all is synchronized without problems.
The nodes for the divas driver are created by the script divas_cfg.rc. Just add your own commands (like
chmod) to your boot scripts after you called divas_cfg.rc.
If no CAPI application is listening on an ISDN port, the default reject-code can be changed using:
/usr/lib/divas/divactrl mantool -c 1 -w"Config/Layer3/RejectCauseNoListen=17"
This example changes the reject code of controller 1 to '17'.
