[103b-0.9.9-1067 port]
Ok, so I tried it with a bootable 2GB SD. The splash screen graphic is the full graphic, unlike when it is loaded on a partitioned 8GB SDHC which only displays the text in the box, without the camera dials graphic above it. "Firm update..." option is available after autoboot with 2GB SD, unlike with 8GB SDHC.
Persistent splash menu when 'show memory info' is activated is still present.
