Sorry, the maximum CacheLines is in fact 1280.
What I find a bit strange however is that increasing VideoRam (default is 65536)
doesn't seem to help at all. I believe this chipset support up to 128MB, and
that's also what xorg log seems to tell when I try to set VideoRam to a higher
value:

(WW) I810(0): VideoRAM reduced to 196608 kByte (page aligned - was 200000)
(WW) I810(0): VideoRam reduced to 131072 kByte (limited to aperture size)
(II) I810(0): Will attempt to tell the BIOS that there is 12288 kB VideoRAM
(II) I810(0): BIOS now sees 12288 kB VideoRAM
(--) I810(0): Pre-allocated VideoRAM: 8060 kByte
(**) I810(0): VideoRAM: 131072 kByte
(--) I810(0): Maximum frambuffer space: 130904 kByte

I tried with mplayer again (with VideoRam to either 65536 or 131072) to see what
was the highest 16:9 resolution that didn't crash.
With the default CacheLines (512), it's 1072x603
With CacheLines set to the max (1280), it's 1728x972
