Hmm, Flashrom found the following (only pasting the same part names, 
well almost same):

Seems to me that's a 2MB chip? Unless the others are 32KB (256Kb) which 
is extremly small. Also in the flashrom there's the whole wyseOS, a gui 
windows like OS which would require more then 256KB I'd reccon so 2MB 
makes sense in that regard as well. So building for 2MB for now :)

Ah, I thought GPLvsa would be the sameas OpenVSA; I don't think I'll 
want AMD vsa I guess, so I'll go with gplvsa for now :)
