Is 0x8801 a register offset?
This appears to be a special sort of register write packet
more or less, but the firmware has some special handling..
Seems like it intercepts/modifies certain register offsets,
but others are treated like a normal PKT4 reg write. I
guess there are some registers that the fw controls certain
bits.

These first appear in a650_sqe.bin. They can in theory be used
to loop any sequence of IB1 commands, but in practice they are
used to loop over bins. There is a fixed-size per-iteration
prefix, used to set per-bin state, and then the following IB1
commands are executed until CP_END_BIN which are always the same
for each iteration and usually contain a list of
CP_INDIRECT_BUFFER calls to IB2 commands which setup state and
execute restore/draw/save commands. This replaces the previous
technique of just repeating the CP_INDIRECT_BUFFER calls and
"unrolling" the loop.

On a6xx the registers are set directly and CP_SET_BIN_DATA5_OFFSET reads them,
but that doesn't work with concurrent binning because BR will be reading from
a different set of streams than BV is writing, so on a7xx we have these
pseudo-regs instead, which do the right thing.
The corresponding VSC registers exist, and they're written by BV when it
encounters CP_SET_PSEUDO_REG. When BR later encounters the same CP_SET_PSEUDO_REG
it will only write some private scratch registers which are read by
CP_SET_BIN_DATA5_OFFSET.
If concurrent binning is disabled then BR also does binning so it will also
write the "real" registers in BR.
