Hmmm, very silent here. I hope I'm not the last man standing.
After a lot of fiddling with the kernel source code I have found a way
to establish a reliable and persistent network connection under
Slackware 11, Kernel 2.4.33.3. The solution to the puzzle here was to
build the network driver as a module, to load the module via /etc/rc.d/rc.netdevice and assign a static ip configuration via /etc/rc.d/rc.inet1.conf, /etc/resolv.conf and /etc/hosts, ymmv.
Involved was a 9595A, P90, 256MB RAM, now with a 10/100 network link. A
big thank you to all who were involved in the driver development and especially to Christian, who sent driver patches and was patient with me.
Here are the netio 1.30 client results.

Looks like I need help. Is there a solution to this or do I have to go
back to Slackware 8 (Kernel 2.2.19)?

The patch and C-file won't work with a 2.4 Kernel out of the box.
I already started porting the sanremo.c to 2.4, but it's not final yet, I have no patch and corrupted my 2.4 Linux partition >.<
I can send it to you for further testing. It's not fully cleaned up, but should compile and give a connection.
Interestingly, the 2.4 Kernel seems to tackle some performance issues: It now seems to hand the network subsystem buffers straight down to the card for DMA.
Seems to only profit in one direction, and degrade in the other.
This is what I measured on an 8595 with Pentium 200, Kernel 2.2:
