Ciao ragazzi, ho un piccolo problema di ricompilazione del kernel su questo ferro vecchio.
Se parto col kernel precompilato non ha nessun problema sulla sk video e vedo tutto tranquillamente a 800x600 e 16 milioni di colori.
Se ricompilo sembra andare tutto bene ma vedo a 65k colori...

Ovviamente col precompilato!
Io non capisco che modulo nel kernel mi manchi durante la ricompilazione... chi mi dà una manina?

e poi l'output degli errori di X col mio compilato... cosa mancherà?
