Just so I'm clear - you're talking about multiple failures for which there are no MELs.
Well, according to the SYS B fail checklist:
The amber LE FLAPS TRANSIT light will stay illuminated until the flaps approach the flaps 10 position.
I suppose you could stop there and use the Flaps 10 QRH landing speeds. Or just keep extending until you're at the end at Flaps 40 and do a normal Flaps 40 landing.
Those are the only two places I can think of where you'd have a good clue of where you'd be.
Oh - Standby
POWER, nevermind.
