12 years ago i change my code to this int main(void) {
AFIO->MAPR |= AFIO_MAPR_SPI1_REMAP; AFIO->MAPR |= AFIO_MAPR_SWJ_CFG_JTAGDISABLE;
and now it working without start up delay.

Hello! May be it is not an issue of st-link, but if I use
AFIO->MAPR |= AFIO_MAPR_SWJ_CFG_JTAGDISABLE; /!<((uint32_t)0x02000000) JTAG-DP Disabled and SW-DP Enabled /
then,next time after power down/up board, st-link do not recognise chip.

I use following code to allowing debug,
int main(void) {
chThdSleepMilliseconds(3000);//allow debug for 3 sec run st-link at this time AFIO->MAPR |= AFIO_MAPR_SWJ_CFG_JTAGDISABLE;/!< JTAG-DP Disabled and SW-DP Enabled / ......

my setup: ubuntu 11.04 x86_64 st-link from git (24.02.2012) STM32VLDISCOVERY -> SW-DP (only SWDIO, SWCLK, GND)->STM32F103VET6 chibios 2.3.3
hopefully this information save some time for somebody. (I use internal loader to recovery my board)
Also "unknown chip id " error could perhaps because program hangs before stlink was running. probably this information should be in readme file.
p.s. sorry for my English.
