the intel 810 should be detected pretty easily by your install progs. it will just be a generic svga driver tho.
i just read a few small quips i found about SoundMax, and it looks like you might have problems with it. it's a card that allows the cpu to do much of the work of the sound card... which is cheaper, but requires a driver... often proprietary. the ac97 kernel modules often can handle this, but i wouldn't guarantee it.
are you getting any errors while trying to install them?
