The issue is here:

ofonod[2536]: Aux: > AT+CGREG=?\r
ofonod[2536]: Aux: < \r\nOK\r\n
ofonod[2536]: GPRS not supported on this device

The correct response to this query according to 27.007 is of the 
following form:

+CREG=?
+CREG: (list of supported <n>s)

Since the hardware simply returns 'OK' (which is not valid according to 
the spec) we do not know what modes (1 vs 2) of CREG it supports.  Hence 
we have no idea how to drive this hardware.  This can be fixed via a 
driver quirk, but we need to know whether e.g. AT+CGREG=2 works...

ofonod[2536]: src/gprs.c:gprs_remove() atom: 0x8f935e0
ofonod[2536]: Aux: > AT+CREG=?\r
ofonod[2536]: Aux: < \r\nOK\r\n
ofonod[2536]: Unable to initialize Network Registration

Same issue as above...  The response to +CREG=? is not valid.
