Not on a Qube2, but on a nasraq, which is essentially the same, just
without the second ethernet port and the pci slot but a scsi port instead.
Last kernel I tried on my Qube2 seems to be 2.4.22-rc2.

Works fine, as far as I can tell.

For me, it's 2.95.4-15 and 2.12.90.0.9-1, and I'm compiling my kernels
natively.

I just tried updating, removing and installing a package without 
any problems.

I haven't tried my Qube2 yet, since that one's already wrapped up and
ready for Karsten Merker to pick up - he's going to send it to the 
Tulip Expert, so those problems may go away soon, hopefully. As to 
kernel versions starting about 2.4.17, I've never had the tulip driver
running reliably on my Qube2, but always got at least 2.4.18 and later 
working properly on my nasRaq (there was some patching involved at times, 
if I recall correctly).
