Working with a 2.5 kernel means a game of catch-up, but it seems I hold up better this time (compared to 2.3). The latest catch-up session included PCI configuration space access API changes and a new serial drivers (I think those are "RMK" drivers, aren't they). I found that new serial stuff basically requires "console=ttyS0,9600" argument if you run a serial console. To work around it in sunsu.c would be counterproductive, and I want to discard sunsu.c anyway in favor of a multiplatform support for 8250.c. I went on and made PROLL to download kernel command line from TFTP server, so now we have a new release of this undying program (I think "venerable" would be too complimentary).
