Ok, seems good.

I found a potential problem with hdpmi: is usually uses IRETD when control is given to the client (switching from PL0 to PL3). That works fine, usually, but may be a problem with NMIs, because IRET(D) - according to the x86 docs - allows another NMI to be triggered. So it might be necessary to implement an IRETD-free path for NMIs ...

However, pondering about that - Jemm also uses IRETD to switch to v86-mode ( there is no other way to do that ), and it seems to be no problem there...
