What kind of Epia? I suppose Epia 800 or Epia 5000. If that´s the case,
disable
tridentfb and enable the cyblafb driver included in the 2.6.14-rc kernels.

Add
video=cyblafb:1024x768,bpp=16,ref=76
to the kernel command line. If that does not help immediately, use
video=cyblafb:1024x768,bpp=16,ref=76,verbosity=2 vga=0x317
and send complete dmesg output after booting as well as lspci -vv output.
There will be a lot of debugging output, be sure to use a big enough
buffer size for kernel messages.

tridentfb timing calcualtion was broken in 2.4 kernels and is broken for
2.6 kernels,
at least for the cyberblade/i1.
