No. The relevant code is in tga.c, around line 269. 
        /*
         * XXX XXX Turning off "odd" shouldn't be necessary,
         * XXX XXX but I can't make X work with the weird size.
         */
        if ((TGARREG(dc, TGA_REG_VHCR) & 0x00000001) != 0 &&    /* XXX
        */
            (TGARREG(dc, TGA_REG_VHCR) & 0x80000000) != 0) {    /* XXX
        */
                TGAWREG(dc, TGA_REG_VHCR,
                    (TGARREG(dc, TGA_REG_VHCR) & ~0x80000001));
                dc->dc_wid -= 4;
        }

I'm not sure how you're getting 1284x1024 with that code present, but
I also don't have a 8-bit board to test with.

Ah, I didn't realize you had a 100MHz box. My as200 is 233 MHz, which
is probably why I don't find it too bad.

Not the zippiest drive in the world, either. I'm using:

sd0 at scsibus0 target 1 lun 0: <QUANTUM, VIKING 4.5 SCA, 8600> SCSI2 0/direct fixed
sd0: 4345 MB, 6144 cyl, 8 head, 181 sec, 512 bytes/sect x 8899737 sectors

which is a little noisy but quite fast.
