yeah, just forgot exact number ..
not sure if it really bug or feature. Should qemu check (and enforce? or just 
warn about?) those parameters, if specific video driver can't cope with 
specific resolutions? 

I also looked at offb sources:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/video/fbdev/offb.c?h=v5.0-rc8

hm, because by default stdvga initialized by openfrmware to truecolor mode (32 
bpp), then I assume cmap hacks not really applicable in this case? I'll try to 
play with switch at line 446 and specifically 'case 32' at line 480 ...
