I'm using v0.99 (latest available).
Also note when I do enable the mysterios "MFGPT workaround" option in

[ 36.780990] NET: Registered protocol family 16

The relevant part would be:
[ 23.092507] NET: Registered protocol family 16
[ 23.105875] geode-mfgpt: 8 MFGPT timers available
[ 23.120247] geode-mfgpt: Registered timer 0
[ 23.133076] mfgpt-timer: registering the MFGT timer as a clock event.
