Yeah, there are lots of solution floating around: Linux Kernel Crash
Dumps (crash to swap like the BSDs and commercial UNIX systems have been
doing for years), console (and memory dump) over Ethernet, firewiring
DMA debugging, etc., etc. There's not much of this stuff in the
mainline kernel, or in the vendor-distributed kernels, yet.
The reason that the BSOD style solution is nice for desktop end users is
that it's easy to get hold of the panic output--it's right there, on
screen.
You can't expect end users to run their Linux consoles to a printer,
over serial, or over Ethernet in the hope that they'll catch a crash.
On the other hand, the other solutions are far more suitable for remote
management of Linux, where a BSOD can become an annoying reason to visit
the datacentre.
