I've tried it. It seems scrolling has a bug, here is what it looks like:

Also, the scrolling is generally slow. Based on what I've seen from inspecting the registers in Bochs, you don't enable caching in the CR0 register, neither SSE in the CR4 register.
Running ish2 creates an undefined opcode exception. In case this is of any use to you, here's the panic information from the screen:
Register state before a panic:
EAX=0x00000053 EBX=0x00000000 ECX=0x0011b7a7 EDX=0x00000000 EDI=0x00000001 ESI=0x00000000 EBP=0x00120e24 EIP=0x0010a2f7
Error code (if present, otherwise 0): 0x00000000
Faulty opcode: 0x0F
Interrupt number: 6
Running bfntest more than once creates "font_draw: glyph [0x0042] not found" and continues with several other glyphs. Then, it attempts to scroll the screen, creating the same effect shown above, and ultimately a divide by zero error.

It seems the system would need better overall stability.
