Good question.  I don't know how to find out what things are hosted at
infradead (it redirects to https://lists.openwrt.org/mailman/listinfo),
but in the linux git history, I found URLs for these lists that are
not on lore:

  barebox             1 link from 2014
  kexec               5 links, most recent from 2021
  lede-commits        1 link from 2017
  linux-afs          16 links, most recent 2021
  linux-parport       1 link from 2005
  linux-pcmcia        6 links, most recent 2010
  linux-rpi-kernel    1 link from 2019
  linux-um            1 link from 2020

linux-afs looks like a good candidate for lore.  Possibly kexec, too.

linux-rpi-kernel seems like it might be of interest and
https://lists.infradead.org/pipermail/linux-rpi-kernel/ still shows
some activity.  Unfortunately the only URL I see in the git logs
(http://lists.infradead.org/pipermail/linux-rpi-kernel/2019-March/008615.html)
is already dead.

The following infradead lists appear to be archived on lore already:

  ath10k
  b43-dev
  linux-amlogic
  linux-arm-kernel
  linux-mediatek
  linux-mtd
  linux-nvme
  linux-riscv
  linux-snps-arc
