It may be possible but it's very limited. The problem is, that Arachne rely on VESA BIOS. And VESA make the standard available later after 286 era when mostly PCI graphics cards was used. Of course there are also some ISA SVGAs with VBE - I have one S3 8xx card with 1MB of VRAM and VBE 1.2 that makes possible to fit 1280x1024/4bit or 1024x768/8bit but I don't know if it really supports 1280x1024/4bit modes. There probably was other ISA SVGA adapters for CAD that might reach 1280x1024 or 1600x1200 but they was not standardized by VESA VBE - in that time there was anarchy in SVGA - any standard so every vendor had to provide own drivers/libs for the hardware. Fortunately later comes VESA VBE and standardized the basic things like services for setting a vmode, putpixel, bank switch, LFB later, etc... But most of VBE enabled SVGA card was for PCI/VLB and come available in age of 486 and later...
