Hi Martin,
In the \os2\drivers\snap\config\graphics directory there is a file 'graphics.log', that will have a log of SNAP initializing and figuring out what modes are available.
I'd start with that, if you want grab it and post it here we can work through it's contents. Take a look at what's included in mine (attached to this post).
Beyond this, whenever I've seen this type of a situation it almost always has been caused by a monitor EDID that SNAP interpreted as something that did not support a particular resolution you selected. The weird thing is that you actually do see that resolution shown but upon re-boot it does not become the active resolution. I would hope the graphics.log file will tell us a bit more about that.
One thing you could try is to turn OFF the DDC detection logic, you can do so by including the following in your CONFIG.SYS:
SET VCFG_NO_DDC=TRUE
That is supposed to force SNAP to using the resolution and settings you specified as opposed to checking the monitor capabilities at boot time.

into making the application-level RDP confgured and tested, but I'll give this a shot within the next couple of days.
