AFAIK they are still limited to a static mapping.
If you check the PowerPC Linux kernel you will find:
/* Add helper information for the Abatron bdiGDB debugger.
/* Context switch the PTE pointer for the Abatron BDI2000.
* The PGDIR is passed as second argument.
I. e. the kernel provides special hooks to update the BDI's knwoledge
about page table use. This is at least an indication that the BDI2000
is not only well supported by the Linux kernel, but also the first
commercial debugger that provided and received such support.
