I can confirm these symptoms on my system with a Voodoo3/3000/PCI and a SiS530 motherboard (AMD K6/2). I get both the "mtrr: ... overlaps existing ..." message some extent of the text corruption. With VESA fb, I get the random lines of colored pixels. With tdfxfb, the most noticable problem is that the cursor is several times larger than it should be (like 1"x1"). Additionally, with the standard console, upon switching from X, 1 or 2 cells with have randomly colored letters in them, and some letters ("h" particularly) always appear incorrectly.
