Here,

The flawed one returns:
> console=ttyS2,115200n8 vram=12M omapfb.mode=dvi:1024x768MR-16 at 60
omapfb.debug=y mem=80M omapdss.def_disp=dvi root=/dev/mmcblk0p2 rw
rootfstype=ext3 rootwait buddy=

The healthy one returns:
> console=ttyO2,115200n8 mpurate=720 vram=12M
omapfb.mode=dvi:1024x768MR-16 at 60 omapdss.def_disp=dvi root=/dev/mmcblk0p2
rw rootfstype=ext3 rootwait

Thank you again.
Regards.
