This may already be apparent, but Dell sells two versions of the 9350:
one with the Broadcom adapter and one with the AC 8260. I just
happened to find the former version at a deep discount at Costco so
decided to chance it. Turns out the Broadcom card is not so good even
with new kernels so I upgraded. Anyway, since Paul is seeing the same
issue I don't think the values are intended to be Broadcom-specific.

Probably not important, but it seems that there is some additional
indirection. The only values I'm seeing associated with those symbols
are 8 and 16:
$ grep -e 'DOM[0-9]' -e 'LIM[0-9]' -e 'TIM[0-9]' dsdt.dsl | grep -v Store
DOM1, 8,
LIM1, 16,
TIM1, 16,
DOM2, 8,
LIM2, 16,
TIM2, 16,
DOM3, 8,
LIM3, 16,
TIM3, 16,

I will keep an eye on the list archive, thanks!
