I'm not sure this will help you or not...

I have the same error messages on my ASUS 1201N Eee PC running Ubuntu 10.04 x64.  In my research, as limited as the information is on this, I found this to be specific to ASUS + NVidia NForce2.  Most people that have this issue write that the error delays booting an additional few seconds; no one has identified the same issues as you that I saw.  Some others report that the SMB issue is with ACPI and a few other NForce2-controlled functions, including some boot-up USB issues.  Yet none that I saw had any issues with video.  (For me, my 1201N won't hibernate...)

Of course, very few of them are running dual video cards and more than 8GB RAM, so your problem could certainly be a result of the error.  OTOH, going from BIOS 4.08 to 6.01 is a huge leap.  Have you contacted ASUS about this problem, or tried interim BIOS updates?

Anyway,  perhaps this link will help:
