Scott, That should do fine. You can also keep an eye on the generated .mem file because pdata access does not set _XPAGE every time. I usually let make echo it to the terminal.
Modifying crtpagesfr.asm may be overkill. The other two are required. OTOH for real paranoia you can use an extra peephole file that replaces MOVX @Ri instructions with NOMOVX so the assembler will give an error. Or even recompile the library with this peephole rule. No XPAGE equivalent when dual data pointers are available is quite common. But it's kind of stupid that they made MOVX @Ri totally unusable. If only they had fixed pdata to 0x80nn.
