I cannot comment on the "sleep mode", but I vehemently disagree that this
power-off should be in gsmd.  This is a phone, not a desktop device with
outboard peripherals with separate power supplies.  When the user turns off the
phone, they expect that the GSM modem is also powered off, regardless of who
(gsmd or other) turned it on.  Even if it was turned on by gsmd, gsmd has a
distressing tendency to segfault, which would end up leaving the modem turned on
as well.  In fact, I argue that this power-off should be part of the kernel's
serial port power-off code, so that even if user-space is so totally botched
that no scripts can run, at least an effort is made to power-off the GSM modem.

Regarding the crashes, that sounds a lot like bug #788 to me - can you test if
one of the resolutions listed therein works, and if so, I guess bug #788 should
be associated with this one.
